    OK I'm in at this price. My first dropper post. Thanks for the lead.

    I know the Kronolog has been known to have issues, but I'm willing to give it a try at this price. I'm curious to see how much I'll really use it during a ride.

    Thanks for the heads up. I just ordered one; figured between Crank Brothers warranty service and the Nashbar unconditional guarantee it's worth a go for $130. Got it for $150 with tax and shipping.

    The guys at by LBS (Arizona Cyclist in Tucson) say they have installed a number of them and haven't had any issues if they're properly installed. I'll have them throw it on, which will help if I need to warrantee it since they're a Crank Bros dealer.

    Here's hoping the post actually works!

    Hmmm, was not expecting this...

    It took 2 emails and 1 week but Crank brothers came through... today I have a new barrel adjuster. Seems the issue is known and switched to Jag cables as they are more flexible and cause less wear.. I tried but they would not send me one.. lol.
    So if yours did not come with a Jag cable check ur adjuster and send them and email.
    I has to sent email to 'info[email protected]' becasue the '[email protected]' kept bouncing.
    Once I heard back from '[email protected]' he said to email '[email protected]'. So hope this helps someone.

    Here is what happened and what I found.
    A week or two ago I went for a ride and for the first time I sat on the seat and the Kronolog went all the way down. I popped it back up and again sat down and it went all the way down again. Naturally I thought the worst. I managed to pull the lever back a bit and wiggle the cable. Seat stayed up. So I figured it was just an adjustment. Got back home and checked it out all looked fine. Took the post out of the bike and took the remote off too. Left it inside overnight, to see if there was a difference. Long story short.. it felt like the cable was bent, in the housing. I could depress the lever, and it would not return fully. When I adjusted the cable tension it seemed to resolve the sticking a bit. Now I did notice the cable was bent a bit at the activation lever end. I figured I just needed to replace the cable. I set out to do just that tonight. As you can see by the pictures, it was the adjuster that was the cause of the issue. It seems that the cable has worn into the adjuster. I will email CB and see what they say. After 5 months of riding 3-4 times a week, this seems odd. It is definitely a design issue. Will see what they say, as I have not seen anyone else post on this issue.


    Emailed the "[email protected]" address and response was "The email account that you tried to reach does not exist".
    I have forwarded the email and the failed email to "[email protected]".
    I did see in the installation video that the cable adjuster was half way out.. not all the way in. I left a little extra slack expecting to tighen the cable if eventually..

    Over six months of regular Kronolog use w/o any problems. Looks like I may be one of the fortunate ones?

    HAs anyone broke the bridge (plastic part that goes between the rails in the saddle)? if yes where did you get this part. I have e-mailed and called multiple times and no answer back.

    Hopefully you mean the piece the arrow is pointing to in the pic.
    I would try to email '[email protected]' if you have not already.
    I know for the issue I had with the barrel adjuster he said to send an email to '[email protected]'.
    no reason why they would not be able to get you one, don't know if they would cover it under warranty though. Hope this helps.

    I have now had mine for a little over a month and have done a few big rides on it. I live in Tucson and our AM rides have lots of rocks and chunk, but also lots of climbing and rolling terrain. First, I can say that I love having a dropper post, use it many times each ride, and I think it made my testicles bigger. Getting my seat low and out of the way is helping me clean all sorts of gnarly tech sections that I never had the balls to clean before. The bad news is that the Kronolog already drops 1/2 inch when I sit on it at full extension, and today on Milagrosa Ridge the air spring apparently blew out and it won't rebound without me pulling on it. I think I'm going to send it back to Nashbar, get my money back, and buy a Gravity Dropper.

    Quick update, after 10 or so months of reliable performance (the ever present 15 mm if initial slip notwithstanding) my kronolog stopped returning. I'm going to contact them and return it.

    I just called Crank Brothers about some questions I had regarding rebuild kit compatibility for my EggBeaters. I talked to Evan and he was extremely helpful. While providing guidance to me about the differences between Candy and EB kits, he said if I buy a Candy kit for my EB pedals, I should just shoot an email to [email protected] and they will send the seals to me. I'm pretty sure that would be the correct avenue for you to get a replacement bridge. I called the number listed on their Contact page and was talking to a live person within a minute.

    I've always received great service when I had questions or issues with Crank Brothers products (just a few instances, but am very happy with their service).

    My Kronolog is still working great and I'm very happy with it.

    My Kronolog finally failed after 8 months serious use. Send it to the shop in germany where I ordered it, it took 3 weeks and today i got mail that it has been fixed and they are sending it back to me. My problem was slipping, could not hold position at all, it happened very quickly, until then it worked like it should. So I thought its the issue with the soft metal / worn out notches on post, im very curious what have they fixed and how long will it last.
    They did not tell me what have they done, so im waiting now.

    S'what I did.

    Got my first replaced/fixed/whatever b/c of the slipping issue.

    Replacement had a jag wire cable set up and a 'new' trigger assembly with a cut-out window indicating cable slack was adequate.

    New post lasted 4-ish weeks and has now blown out all its air.

    Haven't bothered pulling it out to re-inflate it (hopefully will fix it) as I don't have any zip ties (lol).

    At least their office is 15 minutes from mine, which was a primary consideration when evaluating dropper posts.

    UPDATE: If you've been following this thread from the start, you might have noticed that I'm one of the few who didn't seem to have any premature problems with the Kronolog. I had one of the very first batch and it took a little over a year of riding before my Kronolog finally started showing signs of slippage. At full height it would slip down about 1 inch after pedaling for about 50 feet on the trail while seated. I disassembled my Kronolog and found that everything was mechanically fine, but the locking levers were rounded and the stanchion tube had smooth spots where the post was slipping. I emailed [email protected] about it, and he advised me to bring my seat post in for service (I live about 40 miles away from their offices).

    I actually had a cousin bring it in (I work on weekdays and CB is closed on weekends) and my cousin was in and out of the CB office in less than 20 minutes. When I got home from work that same day, I was expecting to just get new locking levers installed for a nominal fee. However upon inspection of the serviced unit, the first thing I had noticed was that the seat post stanchion was replaced with a brand new piece! Further inspection revealed a lot more: In the mechanism area, I found an updated cable holder piece and a new lower cable end that replaced the short aluminum cable end that my seat post originally came with. The cable housing also featured a new semi-rigid extension piece that looked to be kink-resistant. On the other end of the cable, I found a completely new trigger assembly; not only was the trigger all new, but a closer look revealed that it was a new and updated design. There was a new cable spacer inside the trigger spring, and the trigger clamp/holder is a new design, with a notched adjustable trigger angle for better positioning. Nick even replaced my super-chipped bottom cap (long story, involves locking pliers and some impatience!) and filled the seat post up to the proper air pressure. Oh, and yes Ė the locking levers were replaced with brand new updated pieces.

    All of that was done in a matter of minutes (on a Friday afternoon too), and the best part of it Ė I wasnít charged a single penny for the service. I had my Kronolog serviced and updated and ready to ride the next day.

    On a side note, my cousin who has been running a Rockshox Reverb for almost the same time as I have (but nearly not as many miles on the odometer) is in the same position with his seat post slipping; but he has to send his seat post through a local dealer to the SRAM/Rockshox service department somewhere in Chicago, and they told him that the usual turnaround is 4 WEEKS MINIMUM (if they're not busy).

    So I'm still happy with the Kronolog, and on top of that I'm pretty happy and confident with Crank Brothers customer service.

    Here's some pics of my Kronolog and the updated stuff:

    Nick is a rad dude (guy @ CB who does the repair work). However mine's now broken for the third time. I ride 2x/week, MAYBE 30 miles/weekend. Got the full rebuild like Raine, new problem is that the post won't come up to full height (even with max pressure and confirmed torque spec for seatpost clamp). This was a different issue from the previous iterations where it slipped. Another guy I ride with has fore/aft rocking issues.

    Kinda over this thing. Only thing preventing me from a(nother) refurb and selling it outright is the fact that these guys bang out repairs while you wait @ lunch.

    I'm now on my third Kronolog. First one was an original that slowly deteriorated and wouldn't stay up. Second one was a warranty replacement, new which deteriorated after three rides. I should have my new replacement tomorrow, we'll see how that one faires. Nick is great as is Crank Brothers customer service. At this point I think the overal design is flawed.

    Not to single you out or anything... but since you are the most recent person to post, I'm just curious - what do you mean by "deteriorated"? And after only three rides?

    The first one started to lower on its own; at first a 1/2" then it just wouldn't stay up at all this happenedover about five months. The second one started that after the second ride, by the third ride it wouldn't stay up at all. I followed the installation instructions to the letter.

    Now that you mention it, at the first 1" drop it sounded like a knock or pop.

    I'm installing a crank brothers kronolog post but the clamps do not allow the saddle to pivot down (pretty much just up). Am I missing something or is this a serious design flaw? The lowest I can pivot the saddle is still too "nose up" for me (see attached crappy iphone pic).

    Thoughts?

    Mine works great so I would rule out design flaw. That said I don't see any issues with the way you are set up (plenty of cable slack). Have you called Crank or talked to LBS?

    You can pivot the saddle towards the handlebars? If so, I wonder why mine won't allow it.

    Weird - would you mind uploading a picture of the rails in the post? I've attached an image on my post and why I can't seem to pivot the nose further down.

    Currently, there's a ton of opportunity to pivot the nose up and none to pivot the nose down. Obviously if I reversed the post, it would allow a ton of downward nose and minimal upward nose.

    Not a "serious design flaw" at all. Normally the clamp for the saddle has more adjustment on the "back side" compared to the "front side" - if the cable and mech were facing forward, like most installations.

    So - the reason why your saddle is nose up is because of how you're installing the Kronolog - you have the cable and mech on the rear of the post, not the front.

    The solution is simple, no tech support needed from CB: If you want to run the cable at the rear of the post (like in your photo) you just have to remove the stanchion and flip it 90 degrees. That will put the saddle clamp part in a position to give you more movement to level your saddle.

    Good catch. I didn't notice it was reversed. Mine was installed by a CB tech and it is set up forward.

    You can run it either way, so it's not really "reversed" - it's just a matter of rotating the stanchion accordingly =)

    So now I know that instead of running into a major design flaw, I installed it backwards...

    You'll run into the major design flaw soon enough. Not to worry.

    After running this post for a little over 6 months here are my thoughts -

    First one I had, did not come with that magic 2-3mm of slack in the cable. According to CB, this caused a failure. Either way, I sent mine in, they sent me a new one. They said it should have been setup correctly from the factory, which it was not.

    The replaced one came setup with the 2-3 mm of slack in the cable and has been working well, giving it an A- I give it the minus because every now and again, I raise up the post and it will sink down a mm. When the seat is in the down position it moves around a little which is annoying. Overall, it goes up and down as designed. However the annoying 1mm move in the up and down position is annoying enough that I would not recommend this post.

    Well - when there are 7 other brands that don't do that, then yes. Is this 1mm (probably more like 2mm) a precursor to a greater issue? When it goes to the top it should not move at all, as when it goes to the bottem. I'm not selling mine, but if someone asks if they should buy a Kronolog, I would steer them to the Thompson.

    I'm just saying... your butt is probably super duper sensitive to feel a 1mm drop LOL

    My friend just got a Kronolog, and I am not impressed at all.

    First, the action just feels sticky and rough. even on the first day.

    Second, the seat clamp does not work right. It tightens around the part on the post that sets the tilt, but I could not get it tight enough to really hold onto the saddle rails tight enough. The bike shop that sold it to us just used the longest handled torx wrench they has and cranked the crap out of it until it held. When I checked how tight it is, I was surprised they were able to get it that tight without stripping the bolt. I looked up the torque spec on that and it is only something like 12 N*M.

    Third, the sliding shaft looks like it is asking for trouble (and from the reviews, it looks like my suspicions are correct). Why is there no boot for this? You've got an exposed stanchion that has grease on it which is going to collect crap that sticks to it (not to mention you get it all over your hand when you pick the bike up by the post). It has a seal to keep the crud out of the inners, but the shaft is not round, so I can't see how it could seal all that well. Even if it does at first, I would think that the seals would wear at the edges of the flat parts of the shaft. The sales guy said it's just like a fork stanchion. No, it's not. Fork stanchions are round, and you don't grease them.

    I am trying to convince my friend to use the bad seat clamp as an excuse to return this and buy a GD.
    15mm is a second-best solution to a problem that was already solved.

    It shouldn't be slow or "sticky". Swap the post for a new one.

    Mine works great... But it is my second. The first was replaced by CB

    Hopefully we will..... for a Gravity Dropper.

    Seriously, with 2 QC issues right out of the box, and a design that seems (to me) destined to eventually fail, and a plethora of examples from both users and reviewers to validate my concerns, I can't see any reason to not return this for something we already know has a strong track record for longevity.

    I mean, what is the selling point, here? "It might not be as bad as you think" or "It doesn't crap out on some people"?

    I'm glad yours works well. How many years have you had it? Two? Three?

    wow... It's been awhile since someone chimed in who wasn't an actual owner LOL =)

    Anyhoo - like the other guy said, if it "feels stick and rough" that's not how it's supposed to be. mine always moved smooth and linear ever since I bought it.

    Second - The seat clamp works fine, provided you use the included spacer/insert between the rails. You don't have to "crank the crap out of it" - once it sandwiches the plastic rail insert/spacer it tightens up the grip on the saddle rails with maybe 1 more turn.

    I've put more than a year of riding on mine before it started showing any issues (can't be 2 or 3 years, it hasn't been out that long.) Mine was one of the first batch, and when I finally needed it to be serviced earlier this year CB gladly rebuilt it with all new/updated parts for free, in less than 15 minutes, the same day I brought it to them, no questions asked.

    I know that's not how it is "supposed" to be. Nothing is "supposed" to feel like crap. That's the whole point. Poor QC.

    No, the seat clamp does NOT work fine. It is supposed to work fine, and YOURS may work fine, but this one does not. Again, poor QC. We have the spacer. This was not just me, the shop had the exact same issue with it.

    This needed a rebuild after a year? Is this supposed to be a selling point? Are they going to do this for you for free every year? Also, realize that most will need to mail it in.

    Sorry, this is just not at all convincing me to buy one, it is convincing me to stay the hell away.

    Relax guy... =)

    Ok - your buddies seat clamp does not seem to work fine, but mine DOES. So I guess we're both right LOL

    And my seatpost didn't need a FULL rebuild after a year, it just needed new clamps (since it's mechanical friction and the clamps got worn round)... but they rebuilt the whole thing with the newer, updated parts without me even asking for it. In fact, the only parts I could identify that were my original parts were the outer case, the seatpost clamp (which still works =P ) and the bottom cap. They didn't have to replace all of the other parts, but I'm sure that because there are a lot of people having problems with it that it's better for them to do the whole job, and I salute them for that.

    And yes, most people aren't conveniently living within 30 minutes of CB - luckily I was, I was originally going to send it in and they quoted me a 2 day turnaround once they received my seatpost, but I elected to just bring it to them on a Thursday to get it done in time for a weekend ride, thinking I could just pick it up the next day - but they fixed everything on the spot.

    So anyhow... that's my experience so far, and although a lot of people have had issues, I guess you can say I'm one of the lucky ones. Would I recommend the Kronolog to others? I have to two people (I even linked them to this thread so that they can see both sides); one went ahead and bought one (no problems at all so far) and the other one ended up getting a DOSS instead. On a side note, my cousin's Rockshox Reverb won't even stay up after less than a year... and after contacting them about actually mailing it in, they said it would be a 4-5-week turnaround. My brother's Giant-branded Contact Switch, on the other hand, is a lot older than my Kronolog and my cousin's Reverb, has a lot more mileage, and yet it still works buttery smooth to this day.

    Go figure? heh

    Hey guys, I think I got a bad post too. I followed the instructions. It looks like the only thing is to make sure the cable's right and you don't see that evil shape in window of the lever per the directions... which suck!!

    First it worked riding around after I built the bike. Then the post would go down but not stay down. Now it pops up but if I sit on it.. it goes down! The post will work every once on a while. I'm taking the Kronolog to my LBS for them to check out.

    Any other suggestions??

    sounds like clamping part doesn't seem to be working right, it's the same parts that are supposed to hold the seatpost all the way up or all the way down. Try removing the cover to the mech to see if the cable is moving smoothly and that both levers are moving independently of each other... if one of the levers sticks then it won't do what it's supposed to do. Usually the bottom lever hangs up if the cable/cable housing can't move freely when you hit the trigger. Check for any extra grease in there too

    "...delusions... crackwhore... going to hell..."

    My Kronolog is working, how is that delusional? And how would you know if I smoke crack and if so, enough to be a crackwhore? and who told you I was going to hell? Am I on a passenger list? LOL Don't call me out because I'm trying to help those who actually have one and are having problems with it. You don't know me and I could care less who you are, so don't take it to personal level because if you don't like the product or you think it sucks then good for you. That's your opinion and that's fine.

    I built a Dixon for your neck of the woods. I plan to ride it anywhere from the city up to Pemby. While I don't need a dropper post for places like Fromme I would think they would come in handy around Whistler Valley. What post do you recommend? I may buy another if the Kronolog fails.

    Hey Rune, thanks for helping! The Kronolog came highly recommended. I was given a choice of LEV or CB but was told the Kronolog was the way to go. It may be a stuck lever or something. Sometimes it won't stay down and sometimes it won't stay up. I don't get it!! I'll do what you think and then it's going to the shop.

    From a sample of 3 bike shops in North Van and a fleet of test bikes (10) approx 50% of Kronologs fail. Approx 15% of the 1st gen Reverb failed (with the silver collar). Approx 5-8% of next gen Reverbs and KS Levs failed. Insufficient data for Fox, Specialized and X-Fusion posts. Gravity Droppers rarely fail fwiw.

    You are taking your chances with a Kronofail

    Just so I know who on earth recommended a Kronolog to you?

    Umm... that data sucks! So you're saying no dropper post then? Maybe a new Reverb or Lev? something maybe?

    I guess? What would you do? I'm new at all this sub 30 lb AM with no tubes and seatpost that moves up and down. Last time I rode comfortably Numb was on a 2003 Giant AC Air. I rode a Rocky mountain Element 29er rental down Kyber two years ago. The guy almost didn't gimme back my deposit back! I'm just tryin to build something I enjoy riding out there besides my DH.

    A guy on Pinkbike that I bought my Flow EX wheels and XX1 group from. He was super cool to deal with. I think he owns a shop around Chicago. I wasn't from a shop nearby. I bought my last couple DH's from Fantlyk but didn't have six grand to pay from a built Knolly endo or chili. So I lowballed my way around Pinkbike until I had all the parts for this Dixon. Haha.

    yah GD's are pretty reliable. Data from new gen KS's isn't good as they've not been around long enough to really develop an opinion. That failure rate for Reverbs and KS's is actually pretty standard for dropper posts so its best to make sure you can send them back for repair if you need to do that.

    Will I be able to send the Kronolog back without a bill of sale? Like I said I bought the post from someone off Pinkbike. Everything was in a box and brand new. I got an XX1 group and set of Flow EX wheels too but no receipt. He was really great to deal with and did give me a choice. I just went with the cheaper. Funny the only part that wasn't an arm and a leg broke... GO FIGURE!

    OK, OK so I got the post to work. Raine, I took your advice and cleaned up the grease inside. Then I messed around with the cable adjustment basically leaving no tension on the cable at all. Boom!!.. The Kronolog works. I'm still going to buy a traditional post for riding in my home state of MD. I'll keep the Kronolog for times when I need it like my second home, Whistler.

    Now I would like to reduce the travel of the Kronolog. I checked the directions and bought a spanner wrench for the install. I just have one question.. WTF is that spacer in the diagram?? The directions show a blue highlighted spacer on diagram 7. The box didn't come with one and I haven't taken apart the post to find out if it's in there. Anyone know where the spacer is? Or.. Should I just use the infinite control feature to pick the seat height that's right. Do you guys think that would be a pain in the ass? I've never ridden with a dropper post before. I would imagine using it anytime things get even a little techincal since hitting a button's so easy.

    My Kronolog is also working perfect for over a year now. May not have put very much hours on it...but it works. Yes it shows some wear but nothing to be concerned about.

    homeless junkie: i have a seperate spacer in the box. You don't as you wrote. Maybe it is in there already? Did you measure travel to make sure?

    Yea, I checked.. The post is 15.94 inches or 405 mm. I rechecked the box and the only thing left in there is a sticker and the two cardboard pieces that came in the seat clamp. I'm taking my bike in to my LBS to get a blessing that it's safe to ride. I'll see if they have one lying around.

    I'm just glad it's works now!

    It should have come with a small black spacer in the box; if not, your best option is to contact CB and ask them to send you a new spacer (since you got your Kronolog from a forum and not a store). You can maybe find something similar at a craft or hardware store to get a custom height (when the Kronolog is fully extended) but it would have to be made of plastic - not metal or it will score the inner pole, not rubber or it will just wrap itself around something and possibly cause the post to get stuck - with the correct inner diameter to fit on the inner pole thingy

    Like to know how long is the length from top of seat collar to saddle rail during max insertion.
    I read some quote 8.5 inch on pink bike, competitive cyclist and while some 8.75 inch on vital mtb

    Can anyone help confirm the length?

    Just reporting: one more slipping post here. Sent to crank bros for warranty repair. I followed all instructions when installing, i was hyper aware of the need to leave 3mm play in the thumb lever before it engages the clamping teeth.

    I observed the problem is, of the two clamping teeth, the lower one was not returning to fully locked position. I think this is because the cable must move freely in the small hole where it enters the bottom of the clamp assembly. Over time, the cable housing naturally develops some friction here, resisting its free motion, so that it doesn't allow the lower tooth to move to fully locked position. Problem is, once the first skip occurred, its like a permanent problem at that point.

    Bummer.

    Sent from your phone, which i hacked into

    Sorry, I meant i dremeled off part of the post. You know how the locks chew on the post? It looked like the front locks push the post against the 2 locks on the back. And it stayed when it was new until it starts slipping because of grease and yes wear. When new, the post slips like 2-4 mm until the locks get to hold. (Manual says its supposed to happen tho)

    When mine started slipping an inch lower I took it apart and dremeled the parts to make it a little deeper for the lcoks to stay (1.5-2mm deep). The post is thick so it looks like it shouldn't hurt ( and I was desperate.)

    It works for me so far. Ill get pics when i take it apart.

    An update on this:

    Well, the seat clamp kept sliding (despite torquing the crap out of the bolt), so the shop took it back and called CB. Between the clamp and the fact that the action felt a little rough/sticky they were hoping to just get a new post.

    No such luck. Nothing in the warranty about not feeling smooth, it worked, and that's that. As far as the clamp, CB kept having the shop try one thing after another (which the guys in the shop felt was a waste of time), and finally sent them a new part for the clamp (not sure which one).

    They put the new clamp piece on, put the post on the bike........ and now the post does not work

    What a worthless piece of sh!t.

    First, the action just feels sticky and rough. even on the first day.

    Second, the seat clamp does not work right. It tightens around the part on the post that sets the tilt, but I could not get it tight enough to really hold onto the saddle rails tight enough. The bike shop that sold it to us just used the longest handled torx wrench they has and cranked the crap out of it until it held. When I checked how tight it is, I was surprised they were able to get it that tight without stripping the bolt. I looked up the torque spec on that and it is only something like 12 N*M.

    Third, the sliding shaft looks like it is asking for trouble (and from the reviews, it looks like my suspicions are correct). Why is there no boot for this? You've got an exposed stanchion that has grease on it which is going to collect crap that sticks to it (not to mention you get it all over your hand when you pick the bike up by the post). It has a seal to keep the crud out of the inners, but the shaft is not round, so I can't see how it could seal all that well. Even if it does at first, I would think that the seals would wear at the edges of the flat parts of the shaft. The sales guy said it's just like a fork stanchion. No, it's not. Fork stanchions are round, and you don't grease them.

    I am trying to convince my friend to use the bad seat clamp as an excuse to return this and buy a GD.
    15mm is a second-best solution to a problem that was already solved.

    Regarding the rail clamp problem. Remove the rail clamp completely. Pull the e-clips off the rail clamp bolt so you can pull it out. Inspect and clean the surfaces that the rail bolt faces rest on then apply a tiny amount of CLP on the bolt face and the clamp surface where the two mate. Reinstall the rail bolt and clip it in place. Torque to 105 lb in. The rail clamp bolt is supposedly tested to 115 in lb.

    Regarding smooth motion. Disassemble seatpost as per CB instruction. Wipe any "oil" or old grease from inside the body and quill. IMO, adding oil is a bad suggestion from CB on maintenance. Once quill and inner body is clean, apply a liberal amount of light PTFE silicon grease to all seals and friction areas on inside of body tube. Apply thin coat of grease on quill and reassemble. Wipe off excess when reassembled.

    The two arms (for lack of a better term) that lock and position the quill, can get upset from their proper position when the system is taken apart. This will cause them to run out of alignment with each other and you won't be able to get the quill started back into the body or it will go into through the seal and first arm but not the second on reassembly. Have a little patience and study how the system works. With a little manipulation and the gentle help of a long bladed standard screwdriver, you can get the arms to seat back into proper position with the body against the spring tension they are under. Reassemble.

    When you connect the cable to the locking mechanism, make sure you cut it close the pinch bolt connection. If too much tag end is left, when you put the cable cover back on and lock it in place, it can contact the cable end and apply pressure to the locking mechanism causing the seat to slip down a bit when you sit on it.

    I started with a brand new Kronolog that had a similar issue with clamping force on the clamp rail. The clamp bolt remedy was one I discussed with CB tech and it did solve my issue. After taking the system apart to add the 20mm spacer, a significant amount of the original grease was removed just by handling the components with a rag. On reassembly, the quill would not return in a nice, quick, and smooth manner as it had before. Adding oil to the mix was a bad idea as it really slowed the upward return and caused it to function poorly. Cleaning a greasing as I described returned the unit to working flawlessly and smoothly every time. I've had the unit in service for a couple months now with absolutely no issues.

    105 in/lbs would not even begin to tighten on the seat rails. It took several times that toque to get the saddle stable, and even then it could slip. The shop tried everything CB told them to to no avail.

    The rail clamp seems like a pretty bad design to me, because the slightest variation in saddle rail thickness will result in either the clamp bottoming out before they are tight on the rails (if the rails are too thin), or crush the rails before the tilt is locked in place (if the rails are too thick). In our case it seemed like the rails were too thin, but the new clamp seemed to work.

    Bu thanks for the rest of the info on freeing it up when it get's sticky, I'll likely end up using it.

    Update: My Kronolog still works!

    Been riding in Pemberton, Whistler, and Squamish so the Kronolog has come in handy,
    I'm going to rob banks til I retire or get caught. Either way I'm set for life

    Just sent mine back for the 3rd time. 1st time May 2012 a couple weeks after I bought it; second time basically lasted most of the season, started slipping badly, went back in October, replaced it with the "revised" version; now late July early August won't hold air, slips.

    Basically, this post will last between 4-5 months of regular use. honestly I cannot believe Crank Brothers hasn't issued a full on recall of this product.

    Crank Brothers Kronolog Adjustable Seatpost

    I got mine back from its first rebuild about a month ago. It worked great for a while, but now I'm noticing it slipping down just a bit from full extension. It doesn't make the crunching sound as it slips down like before. It just slowly slips down until it gets to the point that I notice it. I can see the green dot in the lever window move off center a bit as its slipping down. I'm not sure what that is all about.

    Well a month of perfect operation is better than the one ride I got originally.

    The lever sucks! Sits up too high and is too thin.
    Has anyone tried installing a different type of lever?

    You can angle it unless you got an old version which only has a one-piece lever mount; the newer one is adjustable for angle.

    I haven't tried a different lever but since the Kronolog uses a standard derailleur cable I don't see why it couldn't be used with anything else that uses regular derailleur cables as long as the other lever moves enough of a distance to release the locking plates

    I've been using the lever ripped off a Xfusion Hilo. Been using it for about a year - works great.

    Hi guys,
    I replaced my Joplin that I stopped using 1.5 years ago because it blew all the oil out the bottom. They offered me the so called upgrade deal and I got the Kronolog. I only started using it because we have a trip next week to Bend Oregon. So it has been moving slightly from the start I was not sure if it was the rails on my seat. Today all in 1 ride it starts slipping 3/4 of an inch but only at my preferred pedaling height about 1 inch from the top. It seems ok when itís at the top of the range and near the bottom too. Just in the middle where itís most used.
    Iíve been using it for 3 weeks. Mostly Iím venting Iíll see what they say tomorrow.

    When you set it up on the bike, how much of a tag end did you leave on the cable end that's enclosed in the mechanism housing? Check that and cut it if it's longer than 2mm. When the sliding housing cover is pushed down and snapped into place, if the tag end is too long, it will impart pressure on the cable end therefore imparting pressure on the locking jaws as if they were being released. This will cause the quill (seatpost) to slide unexpectedly. Worth a look.

    I never changed the cable as it was attached and the length was good. I look at it this morning and at he base of the stanchion the rear track (I have the cable lock mechanism facing forward) you can feel the metal has been scraped off as it the lock just planed nearly an inch of length.

    Do you have the appropriate amount of play in the cable along its run from the handlebars as well as the suggested freeplay in the lever itself? Those 2 things are critical as turning the bars when the cable is taught can cause the seat to actuate momentarily.

    Yep. Had the same issue.
    Cut it short and perhaps bend it as to not touch the cover.

    I'm sure it is setup correct. There is plenty of slack in the cable. At this point if I lower the seat about an inch the area that a thin layer of the metal has been scrapped off is in the area where the locking rings grab and by applying a fair amount of pressure with my hand I can push the seat down nearly an inch more. I should be able to call them now see what they have to say.

    Talked to CB and they are going to fix it and pay the shipping but I won't get it by next Friday. So I paid for a repaired Joplin 4 and they will ship it right away.
    I attached picture to show how it was set up. You can see how at the base of the post the metal is gone and now it won't grab.

    Re: Crank Brothers Kronolog Adjustable Seatpost

    As of my ride today mine is slipping again, 2nd time. Only 30mi on it after it was warranty repaired in June. Yes I'm following the setup directions to the letter.

    Edit: called Crank bros today and they were very responsive, sounds like they're going to make it right. Will update with outcome.

    Gotta give props to CB. Brought my post in with some slipping that started as 1/4" and quickly progressed to 2-3". They replaced it for me then helped me with the new saddle clamp that wasn't too happy with my Fizik tundra 2 saddle.

    These guys have been nothing but helpful in dealing with this product.

    Frankly, with all the problems ALL the posts on the market have, this is the only one I'd consider keeping around given I can just drive down there at lunch and have them check it out for me. Not really interested in being a $400/pop guinea pig for other manufacturers.

    Wish all the best of luck. Mine has survived some serious abuse and has only given slight problems.

    Mine is also going strong! Since one and a half years now. Wear doesn't look at al like the pic from Datman. Although my bike is not ridden weekly it has seen some mud and several weekends in the Alps. Actually...I use it more doing XC/trail than using it in the mountains were it is up for climbing and down for downhill.

    And the post is sold overhere for 200 euro / $270. That's about half the price of a Thomson or Fox. So when it goes bust....simply buy a new one

    That's like a joke right? My specialized cost me $250 (retail 275), simple air-spring with lock mechanism controlled by a cable. Not much to go wrong, same with many posts. There are ones that have great reliability track records, and ones that have pathetic ones (Crank Brothers). This is the company that tried to glue to halves of crank arms together that can't even figure out how to make cranks...which is in their name.

    Check Bikebling or Pricepoint. Bikebling with a code will get you a LEV at a decent price. Wise decision.

    I've been running a first generation Crank Brothers Joplin for 5 years without issue. So I guess each unit is different, some have problems some don't.

    I am so glad I came across your post.
    You see I broke the krono- plastic piece that seats between the saddle rail and clamp on my seat posts when I was installing my new saddle. I needed that piece so badly and don't know where to get one. You mentioned on your post about requesting parts at : [email protected] and they did respond quickly. They took my information for now and I am waiting for additional information from them.
    Thank you for that vital information you shared

    Customer service is definitely their strength. When I got mine back (the 2nd time in a year) I sent it back, they sent me another plastic doo-hickey spacer thing that goes between the seat rails. Seems the "old" one I had seemed to have worn or something because about the same time, my seat wouldn't stay in place. I popped the new one on, and it's back to working again.

    This is now my back up dropper seat post. Ordered my KS Lev and it is on it's way.

    I used mine 5 to 6 times a week everyday. First round, it was about two weeks before it had issues. Sent it back to CB and they fixed it, and sent it back. It worked until September. Sent it back again, they fixed it for free (minus my time and shipping) and sent it back fixed and working even better. Seems they replace the post (the part that moves up and down) because the locking washers eat into it and wear it away until it slips.

    After two failures, taking total time of 3 weeks down time, I bought a KS Lev. So far so good. Kronolog is currently fixed and sitting in the parts bin. The KS Lev, though more expensive, so super smooth, takes little effort to activate, the lever is small and compact. Shame the Kronolog didn't work out. I liked the way it looked.

    If you want this seat post and it fails, CB will take care of you. The main issue is having slack in the cable. That was the first reason mine failed the first time. The 2nd time..I don't know, I had slack in the cable. So who knows. CB will get you back up and running for sure.

    orastreet, that "post" portion you refer to is called the quill. Did you notice whether or not there's anything different about that piece on your latest repaired unit? I ask because after all my "promotion" of this dropper post, I'm in the exact same boat. The softer malleable section that is supposed to grab the locking tangs has worn itself beyond tolerances in about 3 months of use on mine. It started dropping about an inch on it's own a couple weeks or so ago and has changed my pedaling geometry and my knees are feeling it. I'm wondering if they have utilized a different material that can withstand the tangs digging in. If not, there's no way these droppers will last unless CB wants to send us owners a supply of quills.

    I called CB 2 weeks ago and was transferred to someone that was able to deal with a question I had about having them just send me the quill and I'd send the bad one back. I caught a voice mail and no return call, yet. Riding is part of my surgery recovery routine I've been battling and I ride nearly everyday. The trails I ride, I can't imagine being without a dropper now that I've been using one! I, like so many, would never be without one! I've had the unit apart several times and know the ins and outs of it so I'm hoping to just get what I need to make this work again.

    Email them... You will have a reply in 24 hours or less.

    For what its worth I had a problem on mine after two months. They replaced it with the updated configuration. I have had zero problems since. That was 1000 miles and at least 150k elevation gain ago.

    My original Kronolog was one of the first ones, eventually it failed after a year or so. Then it was repaired, ( by CB german distributor) and it failed again.
    Then I contacted CB and told them my kronolog adventure, and they promised me a new one. I just received it yesterday, completely new, with some modifications. Mine one came with a protective neoprene sock over the whole post/stanchion
    Other than that I don't know what is new, I mean something that hasn't been mentioned here already.
    Didn't have time to go out and test it since I'm still building my new bike.

    Interesting! They received mine last Monday. They said "No worries" and they'd make it right. I asked about modifications to the quill to prevent this from reoccurring and was told they made some mods internally and that the release mechanism will be better and feel better. We'll see how that goes. I wonder if mine will come back with a fancy sock?!

    Mine arrived tonight via UPS. They just sent me a completely new unit in it's box. I was pleased to hear that's what they were doing! And yes, it has a sock like the one pictured above.

    First thing I needed to do was disassemble to flip the quill around and install the 20mm spacer on the internal shaft. It works best for me to have the cable coming off the back of the seat post. Problem is, I can't get the internal spanner nut to break free. It's torqued like MoFo....BIGTIME! Gonna try a different spanner wrench tomorrow.

    Regarding people jumping ship to KS LEV....I was seriously contemplating that and just selling my new Krono. That is until I started reading recent horror stories about the LEV and their customer service that have just started popping up here on the forums. It would seem KS is not without it's significant problems as well. Things that make go "Hmmmm".

    I have a Kronolog, and a KS. The KS I bought after my second Kronolog failure. Seems that KS is not without issues either. It's back in Foot Hills CA now on it's second repair. So I have resigned to keep the Kronolog as it seems to be working until the KS comes back. The KS, when it works, is much smoother and refined. It is also 150mm which is important for tall guys like myself. So the Lev is the preferred post. Customer service with KS? When I got Ron Easton on the phone, he was very helpful and seem unhappy that my post failed twice. He offered a quick turnaround on the repair. I am not interested in beating these companies up, I just want the post(s) I paid for to work !

    No. All it takes are the 2 rail clamps and the push button on the handlebar release.

    I know that part... I was asking if there's anyone here that actually bought the parts to do the color change, because that means they have the original red/black trigger that I'm looking for =)

    Can't tell what mod you did from your picture. What did you do?
    Also is your post the newer version with the sock over the seat post?

    Looks like the spring is the mod? Creating more locking force to minimize any slippage maybe?

    Thanks mojo. When my ver. 1 post was slipping from day one, I tried using a flat bladed screwdriver to push down on the bottom dog
    to increase the "biting force" against the post to no avail. Sent it back. My ver.2 post (with sock) has been good so far.

    NO prob I am looking at the Kronolog as I love my Specialized Black Lite and prefer mechanical locking to hydraulic. And the cable placement is really what I am interested on the Kronolog but I have also been trying to get a good sense of how good the 2nd gen posts have been. Seems like they are performing much better than first gen.

    It's really too bad CB didn't take the time to work out the bugs before releasing the Kronolog because the revamped posts are actually quite good. Had they it could have been one of the more popular posts; but now I'm not sure they will be able to overcome all the bad reviews.
    I have one as a backup to my Lev. It's not as smooth as the Lev but no question it's a solid and so far reliable post. When you break it down it's actually quite simple mechanically which in the long run isn't a bad thing.
    Compared to other posts -- the Lev, Reverb -- it's so user serviceable which is a huge plus.

    If you are in SoCal I would take your bike in. Usually same day if not less than 30-45 min.

    Also, I heard over the weekend that they might be about to drop version 2. Could be true as they have been sold out for a while now.

    NICE! So glad to hear that they are standing by their products. I use several of them on both the mountain bike and the road bike.

    I'm about an hour drive from the factory, so I might make arrangements to visit them soon.

    Anyone thought about tinning the end of the cable to make it more robust for the set screw to clamp? It doesn't take too many times of taking this thing apart and back together again before that set screw chews up the cable end, making it hard to reinsert.

    I like that spring mod idea.

    Bought my Satori with a Kronolog post on it 2 weeks ago. Its already slipping. After reading thru this thread, I have adjusted the cable to make sure it has slack but haven't had a chance to ride it yet afterwards, as I currently have the Fox fork sent out on a recall.

    I put a dab of super glue on the cable tip. If yours is new, make sure you cut the cable no more than 2mm beyond the clamp otherwise when you replace the sliding cover, it can contact the cable causing the post to actuate allowing it to slide. I never thought about tinning since once my post is setup, there's not much reason to disassemble it.

    Thanks for that tip. I'll check that.

    On top of the seatpost beginning to slip, it also wasn't coming all the way up, like it didn't have enough pressure in it. That's the initial reason I took mine out, was to check the pressure in it and add some. Had like, 3 lbs in it. I put 10 in it and its much better.

    But man, if you had to do that very often, I guess to avoid taking the cable loose at the seat post, the only other option would be too remove the lever at the bars and hope you can pull enough cable slack thru the frame, eyelets or whatever, to get enough to get the post clear of the frame tube so you can work on it.

    The max psi is 55#. Stick 40# or so in there and call it good. I haven't adjusted the air since I installed it months and months ago. The newer generation of Krono will settle maybe a few millimeters when you sit on it. This is mentioned in their instructions and not a flaw or slippage. On my set-up, I'm able to turn my bars to max right and this gives me enough slack in the cable to pull the post out of the seat tube. The newer generation did, in fact, come with a slightly shorter cable/housing than my first unit.

    I got my 1.5 year old Kronolog from service.
    Looks like they made a bunch of changes to my original version.

    The new Kronolog was shipped with the cable wrapped in a sticker with a pic of a zip tie and a red X over it.

    So Crank Brothers expects the Kronolog cable to be installed with no zip ties???

    Are we supposed to have the cable flop around from the seatpost to the handle bars?

    linger, did they just service your post or did they give you a new one with the lizard skin cover over the seattube?
    I have no idea if that's what the picture means as I have mine ziptied to the dropper post mounts my bike has.

    blcman - mine came back a mixture of new and serviced parts. The base is original, as well as the anodized seatpost clamps and beat up plastic rail spacer.

    The telescoping post looks brand new. They replaced it with a new cable where there is a 6" section exiting the post that is very stiff and not "kinkable". The remote lever is brand new and different from my OG version. The jammers look brand new as well. They added a neoprene lizardskin over the telescoping post.

    I have no clue how to install this without zipties.

    If your application requires zip-ties, just secure them loosely so the cable has plenty of free play slop. Securing the cable taught can create problems for the system, sometimes causing it to actuate just from the tension of turning the bars. In my application, I have no zip-ties. It routes from the left bar grip, around the right side of the headtube, back under the top tube going right to left, and then reaches the post on the left of the seat tube and into the post. It doesn't hang out and works very nicely.

    That's how mine is mounted. Every mech loses his mind when he sees it, but its kink/bind free and works.

    The way I understand it is, its not that there can't be zip ties securing the cable anywhere along its length. You just need to have enough slack in the cable between the last zip tie and either end of the cable where it connects to the lever at the bars and at the seatpost, so that the cable doesn't go taut when turning the bars side to side and you want enough slack at the seatpost end so that when activating the lever, the movement of the bottom locking pawl doesn't pull the cable taut.

    The rest of the cable in between can be tightly zip tied to the frame. That's if the stock cable length is long enough to permit it for your particular bike.

    Also, turn the bars to your max realistic turning angle, side to side and make sure you still have slight slack on the inner cable at the lever(lever freeplay).

    I've seen an 8" section of cable housing they use at the post end that will accommodate the "cable compression".

    Mine has an "S" bend on the frame leading up to the post....

    So when you sit on it, the post drops down of its own volition, and this is considered normal? Before it was a flaw but now that they have written it in the directions, it is a normal feature. LMAO!

    I can't wait to see if the other brands see this cool feature and try to incorporate it onto their seat posts. That must really serve some good purpose when riding.

    It moves a mm or so... Let's not be dramatic.

    This.

    Very much THIS.

    The settling was just a tiny little drop of maybe 1/8". I'm uncertain if it's still doing that as I don't notice it one bit. Literally not worthy of any attention. Still riding it over 30 mi and 4000' of climb a week . Not the slightest hiccup.

    I'm glad you like your post. I liked mine too, before it started slipping to the point that I did notice it but that is neither here nor there. I am not trying to talk you out of liking your post but would you mind if you had a "fixed seat post" and it dropped a mm or so while you rode your bike?

    That is my point. When it isn't being adjusted, it is supposed to act like a fixed seat post. If a fixed seat post moved a mm or so, most people would consider that to be a faulty product. If it doesn't bother you then that is good, but I as a rider like for my bike settings to stay where I set them.

    It only moves 1 mm in the fully extended position. Adjust the seat post QR correctly and no problem... To reiterate, no 1mm drop in any other position.

    Wanted to check in and see how the V2 people were doing. My V1 was a slipper, but performance was overall more solid than the 2 Lev's I've had. I can live with 1-2mm of vertical give, so long as the post goes up and down consistently. Looks like the V2 aren't available anywhere right now - did they improve that much?

    Same features as V1 but they increased the size of the plate/lock (don't know part name) from 5mm to 10mm. End result is a much stronger/more durable mechanism. They also now include a neoprene sock that protects the post from dirt/etc. I have two, one has a year of problem free service. The other is only a month into duty.

    Mind if I ask where you bought them? I'm having trouble finding any online at the shops I frequent.

    I bought the second when I saw it on sale 6-8 months ago. Just now have the frame to put it on.

    I actually need one for my wife's bike and I have not been able to locate either. Crank Bro won't quote delivery either which makes me think they may have a true update in the works.

    Crank Brothers Kronolog Adjustable Seatpost

    I just sent mine back in because it was slipping a lot in mid stroke. This is my second time sending it in. The first time it lasted 6 mos. This time it lasted a year. We'll see what I get back from CB.

    Hi guys,

    I just ordered a kronolog from a german site (bike24) at a very good price, and i wanted to ask, is there a way i can tell if it is the V2 (i presume this means version 2, the new one made in 2014) or the original ? From what i searched around i could not find any visual differences. The site says it is made in 2014, but i don't know ...

    Thank you.

    Not 100% sure about it but when I got my V2 back from CB, it had a neoprene sock that covers the quill shaft and seat bracket that keeps dirt and junk from getting on it.

    I noticed the same a while back. They must have ditched it.

    My V2 is still going strong. Just pulled it all apart a week or so ago for maintenance and cleaned it all out and regreased the guts. Nice smooth operation and the quill is still in great shape.

    Crank Brothers Kronolog Adjustable Seatpost

    I recently got a brand new replacement for my third warranty claim...started sagging again within a week.

    I chose a Reverb for my new bike. So far, so good after 4 mos. We'll see how it does long-term.

    Spring

    I suggested the spring to them what seems like a long time ago.. never did hear back.
    What spring did you use?
    I'm waiting to put the spring I have on once it starts to drop again going over rough stuff, but so far this one is holding up since April.

    I'm late to the party but wanted to order a beer and throw in my 2Ę.

    I too just noticed that the Kronolog is no longer on the CB website. There is no mention of it other than some maintenance stuff, but even there the actual instructions with images is gone. What they have refers to images that aren't there...

    I've been running the Krono for about 16 months and I'm on my second one. The first one died one day where it lost pressure and would not come back up. Crank Bros sent me a new one right away. No problem. I've had this one now since December 2013 and from the descriptions on this thread, it looks like a v2. Within a few weeks it developed a little teensy bit of play in the stanchion. My old Gravity Dropper did this, and the Thomson post a friend rides does this. The only ones that don't among my normal riding group is KS.
    This play would not be an issue for me except it's gotten worse, and now it's creaking like hell. The seat feels squirmy while climbing, even. It's about 3-4mm back an forth, and maybe 5į rotationally. Really no good.
    But my very least favorite thing about this post is that ridiculous single-bolt T25 clamp. I've run a lot of posts over the years, and I've never had to carry a torque wrench around to adjust any of them until now. Why in the world would CB use this single bolt, and why a Torx? I've stripped the ends off of six T25 wrenches in a year. "You should have torqued it to spec!" you say? Really? At 12nm this thing rocks with every hit, and the seat slides around in the clamp. It takes more like 18nm to lock it in place. And even at 12, the clamp then won't move from the post head. So again, the seat moves with riding forces, but won't move so I can adjust it. It knocked out of position last night, but even once I removed the bolt, the clamps held tight and I couldn't move them back into place. And had I been able to, I was only carrying a multitool (CB, with the T25, natch) which in no way would have allowed me to tighten this correctly. I made do and cut the ride short.

    So while I still have this thing on my bike (as I'm planning to replace it with the KS or Thomson), anyone have any suggestions?

    I've owned the Joplin, Kronolog and Reverb. Have tried the Thomson. Currently own the KS Lev.
    I recently bought a FOX DOSS and it is by far my favourite. A hugely under-appreciated dropper post.
    Absolutely bullet-proof, smooth and very robust.
    I think the partial drop feature (40mm) is a game-changer. It is the perfect height for when you don't need full down but want a lower post for technical manoeuvres. Low enough to add a huge sense of confidence but high enough to still pedal well. Yes you can get that lower drop with the Lev, Reverb. Thomson but I really like the ability to instantly get in that sweet spot.
    I understand how the lever is an issue to some. That said, If you're running a 1x (and use it where you would the front shifter) then it is PERFECT. Acrually the best of all the levers I've tried.

    Thanks -- what I meant though was suggestions about the Kronolog and the issues described. I have a friend selling his KS Lev so I'll be replacing the Krono with it, but it would be nice to find some workarounds with the Kronolog as well. Especially with the clamp issues.

    Regarding the clamp issue....been there, done that, talked to the techs about it. That bolt has 2 circleclips holding it in place. Remove those and remove the bolt. light grease the back of each bolt head, the part that mates against the clamp. Reassemble. Apparently this allows the bolt head to rotate more freely. The opposite side is indexed in place, IIRC. Torquing is more effective and the clamp should lock the seat into position. I found the fix was a successful solution but no matter what you do, that frikkin' clamp will seize in place making adjustment a PITA, including requiring a dead-blow hammer to get the stupid thing off the quill when you need to disassemble it. That was indeed a piss-poor design. Talk about reinventing the wheel!

    I'm considering the KS LEV for a replacement but even those were not without their own problems for a while, there. It's a clean install, though. My Krono just won't die so it might be a while....we'll see if I didn't just jinx myself!

    Looks to me like Crank Brothers finally decided to cut bait on this poorly thought out product. When the thing worked correctly, it was a decent drop post but I have serious doubts Crank Brothers put in the actual time testing this product they claimed that they did before they put it out into the market. This thing should have had in house testing as well as giving it to some professionals and weekend warrior types to test it out in the wild. If they had done that, they would have immediately uncovered the persistent problems that plagued buyers. This was the first bike product I have ever bought that failed so quickly (within a week) and so completely (three different posts--all failed).

    If you think I am too picky and judging Crank Brothers too harshly, consider this. I bought a LEV after trading in my Kronolog for store credit and have had no major problems with that seat post. I then bought another LEV for my other bike and have had no major problems with that seat post either. In fact, the only minor problem I have had with either of them is the seat clamp can occasionally loosen up but that can either be solved with carbon paste or by checking the seat for any looseness on a regular basis and tightening the screws.

    I say good riddance to this P.O.S but am sorry for you people that stuck it out and tried to make this thing work. Crank Brothers has its detractors and in my opinion, that is for good reason. When the first buyers like me complained this thing was defective, we were told it was our fault because we were unable to install it correctly. Blaming your customers for mistakes made during conception and implementation of a product is a bad idea.

    JP, excellent reply and exactly my experience. My Kronolog failed multiple times, and had a pathetic seat attachment. I now own 5 KS Lev's between my sweetie and myself. This should serve as a cautionary tale to KS however. Their customer service is very poor and they have shown no intention of improving their seat attachment design, which also has some faults, though none fatal like on the Kronolog. I hope they are listening.

    Crank Brothers Kronolog Adjustable Seatpost

    Seems like there is no one single dropper post that would be without issues.
    Been thinking to buy new Thomson covert, havent read any reviews about it but i guess it has some issues too. How hard it can be to build proper one.

    Hi. I have Kronolog seatpost and would like to ask you if this or. so much side to side movement is normal and if not is it fixable?

    That's not normal. It looks like the latching mech is also going from side to side. Is the entire post not clamped in enough? I could not tell from the video. If the post is within two years, Crank Brothers will warrenty it...sometimes even if it isn't. FYI: They have stopped selling dropper posts. They gave up. If you are forced to get a new one, the Tompson Elite Covert dropper is problem free and one of the strongest out there. Not cheap though, at almost $500.

    It's easy to fix. Disconnect the bolt or QR holding the post in place. Then carefully remove the cable and actuating trigger. Gather these up and place in the nearest garbage can and buy something else.

    Ok, well not really helpful answer....
    I have contacted Crankbrothers and I hope they will be able to help me somehow since some of you have a positive experiences with their support service.

    Sure it is. There is no point in fixing the post. Buy something else.

    The locking clamp jaws that you see moving in unison with the quill (shaft) are eccentrically shaped and are captive and spring loaded into eccentric shaped channels in the housing. There is some movement normally but yours looks a bit excessive. Perhaps the housing has been worn internally where the clamps are located allowing them room to twist. I don't recall mine ever having that much play. The primary issue with the unit has always been the quill wearing and allowing the post to compress when weighted. After mine was upgraded, I never had an issue with it but it's been out of service since the end of October when I bought a KS LEV DX 150. My Krono is still functional so I'll have to check it and see what kind of rotational play is present.

    I haven't read this whole thread so I don't know if someone else has had this experience.

    I have had little to no problems with this post for nearly 2 years. I would say that I have been 90% satisfied until the other day.

    While standing up and pedaling I exited a rock garden and hit the lever to raise my seat. The seat shot completely off of my bike. luckily, it hit me in the ass on the way out so I knew that something had gone wrong, if it didn't I might have sat down on the remaining seat post piece and been seriously violated by it.

    Unlike a lot of people I have not had problems with Crank Bros. support so I'm going to call them about getting a trade in. We'll see what they say.

    Haha. That happened to me too (seat popping out). Luckily it was at the very end of my ride.

    My incident was actually at the beginning of my ride. I jammed the seatpost back in. It no longer raises on it's own but I was able to use it pretty effectively by reaching down and pulling it up while pressing the lever.

    I've had a Kronolog on my bike for 2,300+ miles, I use it constantly on every ride. It just recently started slipping mid travel. Took it back to Crankbrothers (live in SoCal) 15 minutes and $35.00 later I have a post good as new, looking forward to another couple thousand miles. Bike parts eventually wear out, I've gotten my money's worth.

    I'm sending mine back in again after 6mo. on the previous repair. That make it 4 times now. I've been switching over to the newer GD Turbo LP on my other my bikes.
    I take the seat post out and drill holes for 2 other positions so I have 4 positions to use.
