    When I mentioned the zip-ties it was to hold the seat post's clamping mechanism (the two levers) together so you can slide the seat post in/out while trying to get that silver metal ring out =)

    I'm digging the looks of these. I may pull the trigger here soon.

    I'm also thinking that this post might be the best. Mechanical stuff is easy to repair and adjust.

    Anyone have any more ride reports of this thing yet? There's, like, 3 people on here who have given their views. There must be heaps of kronologs out there in the field now.

    Lurkers, stop sitting there, give us your opinions! And more pics, please

    I just shipped my old Maverick Speedball R/Joplin today for the trade-in program. I think the trade-in program is a very sweet deal, and I'm really looking forward to trying the Kronolog out on my Mojo HD.

    There is indeed another thread in this Forum regarding this post. Might be worth a read for those really interested in this dropper post. Bottom line, after 6 rides I'm pretty disappointed and have to rate this product (or at least the one I received, as my reviews are based on a sample of 1) a big fail. The link below should take you to the other thread if you are interested in the details. The other thread was started by MTBR member gibbons, and he has some good info on the post, and also had better luck with his...

    yeah, ronski, you're one of the 3 reviewers I was talking about

    Doesn't sound like it's going to be a winner, too bad, I was really excited about this one.

    Like someone else has said on here, they should have used a coil spring instead of air and it would have been perfect. The locking mechanism is the genius in the design, who cares about an air spring. Make it a real spring and it would be so much more reliable, it'd be like a GD with looks - imagine that.

    I've only had a couple of hard rides with the post installed but so far it's been working flawlessly.Well, almost.The barrel adjuster on the lever tends to wind itself back in on really rocky/bumpy rides.Other than that everything's been perfect: no pressure loss, smooth and controlled action, no sloppiness.I can only hope things stay the same in the future.The barrel adjuster problem is easily remedied anyway.

    I've done probably 6 or 8 rides on it now. The button seems to not be as notchy (I think someone described the cable exiting the barrel adjuster towards the lever as making a sharp bend and possibly causing the multi-stranded cable to rub along the ribbing of the strands, this seems like part of it), mine is holding air, returns at a comfortable rate, and still has no wiggle. One thing I'm noticing though is that the quill, as CB calls the moving shaft, is getting notched on the rear silver strip from the plates wedging against it. If it's in one of the notches I notice that I have to unweight the saddle or else pressing the button is pretty hard. Front side is still smooth. I do weigh 215 with no gear. I'm calling them about this today because I'm concerned that the little notches will act as serrations and eat through the rubber seal. Also because I think it could be smoother to release.

    Oh, I also lost my removable cable cover in a small tumble yesterday. I didn't notice it was gone until I was back at the trailhead. I emailed them to see what a replacement costs. Would be nice if they had a set screw or something but it's mostly my fault.

    So far, still liking the post and loving having an adjustable post, in general.

    NO! The plastic thing is holding your rails apart so the tighter you tension the saddle clamp, the more inward force your saddle rails are getting. It should be like a vice where your saddle rails and the plastic insert are being held in compression by the saddle clamp.

    I just looked at the instructions, the bridge that goes between the clamps is loose even after i tighten the screws. I left the shop so I dont have the tool needed for the screw.. will try to loose it again to see if theres something stuck somewhere.

    What saddle is that? The rails look larger than the rails on my saddle so I'm wondering if this style of clamp can handle a larger diameter rail. Still, if you've tightened down the bolt to the specified torque I'm surprised that it wouldn't push your rails in until they were squeezing the plastic thingy. I went and felt mine and it is pretty tight in there, doesn't budge.

    The seals don't mean much on a mechanical post. Those seals have nothing to do with the air spring, so as long as it doesn't get sloppy then no issues.

    it seems that the serrations, in conjunction with the metal plate clamping mechanisms, is a recipe for undue contamination and slider / seal wear. degradation of the post surface over time looks inevitable. time will tell, of course...

    After cleaning it off and feeling around on it, It's not as serrated as I initially thought. CB said that they did have one prototype that had slightly deeper notching than normal but that it worked itself out over time, with the clamping and unclamping of the retention plates. They said I could return it to let them look at it and either attempt to make it work perfectly or warranty it. I'm going to see if it works itself out and send it in if it get's worse.

    they also explained how the post slippage thing happens and why it would be caused by improper installation.
    -cable is installed without enough clearance to move up and down as button is pressed and released.
    -button is pressed, post releases from plates and is moved under rider weight, and then the button is released but doesn't fully release due to the cable clearance. So it's as if you partially pushed the button. This causes the plates to not "bite" into the post well.
    -Rider places weight onto saddle, post slips due to the plates not being allowed to properly grab the quill.
    -slipping post causes the mating surfaces of the quill and plates to wear down and not grab onto each other as well. At this point, even if you correct the cable routing, the damage is done and you'll keep getting slippage which causes even more damage.

    made sense to me.

    Makes sense to me too but it also seems this is a major weakness and possible point of failure. If the mating surfaces can wear down that fast, it points in the direction of the system not having long term reliability. We'll see as more users get their hand on them.

    OK so bad news mine is going back after just a month's worth of riding due to a failure. Just to give you and idea I'd estimate it has less than 20 hours on it. I get to ride about 3 times a week maybe 4 hours total. I'm 150 lbs, 5'7" and not really an aggressive rider. Although I do use it a lot because I've really been trying to practice my cornering so anytime I'm on a downhill I'm dropping the seat. For a month the thing worked flawlessly. Install was easy and I worked really hard to make sure I did it right. About an 1/8" play in the lever. No binding in the cable (I can completely rotate the the handlebars either direction). But yesterday I got maybe 1/4 mile into my ride and hit a rock and felt something weird. Felt like the seat dropped just a little. Sure enough hit the trigger seat pops up maybe 1/8-1/4 inch. Well I'm thinking maybe I didn't have it all the way up when I started. Nope. Hit another bump felt the same thing. Push the button post comes up same amount. So I ride my loop, all of 3.25 miles. When I really get into a rocky climb the post drops more than 1". Probably like 1.5". Enough that pedaling just feels wrong. Get to the top and start messing with it and all I have to do is sit on the saddle and it drops 1/8". Then give it a little bump with my butt and it drops more than an inch. Get back to the truck and pull the cover off. I can push it with my hand and see the bottom clamp deflect down. That's my 1/8" drop. I shouldn't be able to do that with my hand. Then give it another harder push with some body weight and the post slides down like butter until it finally bids after moving more than an inch.

    1 month guys with nowhere near as much riding as many of you do. Keep this in mind if you decide to purchase.

    Now good news. I immediately call CB and talk to a guy named Nick. Super nice and understanding. HOWEVER he did tell me the movement on a smaller scale is a known issue that has just started popping up in the last couple of days in New In Box stems. He said there are some tolerance issues coming out of Taiwan with the binder stem interface. Where the tooth on the binder(s) doesn't bite into the post. He was surprised to hear I had no issues for a month. My inclination is that on mine the binder interface has worn way so that it no longer bites into the post.

    Now my biggest fear, send my 1 month old $300 plus bike stem back to them for repair. I really wanted to blow up at that point as anything like this should have a 30 day no questions asked replacement or refund as long as the owner hasn't done something stupid. The the deal was they sent me an RA through email to ship it back. So there's a week in shipping just to get it to them. Then they'd repair it the day it got in and ship it back. There's another week. I told him that time frame didn't really seem right since the thing's practically new and shouldn't they expedite that and ship me a new one while the old one was on it's way back. He said he could check on that but didn't sound hopeful. So I pushed for express shipping both ways and he said he'd try that. So I'm really trying not to loose it since I knew buying this 1st generation and with CB reputation what I was probably getting into. But still it sucks. And for all of you thinking about buying one I'd strongly suggest waiting. If I had it to do over I probably by the Giant Control for $100 less than the Kronolog and local dealer support. Although I did my Kronolog from a local deal they got it special for me so that's why I went directly to CB.

    So post failure very bad, very unhappy. Customer service pretty good. I actually got an email from Nick about 5 minutes later that they were shipping me another post the same day (yesterday). So somehow he managed to swing that. For which I am very thankful. But it shouldn't have failed so quickly. Unfortunately they didn't ship it expedited so it's still going to take a week for it to get to me. Kind of cheap in my opinion considering 2 day UPS probably would have only cost them another $10 and would have made me a very satisfied customer with their customer service.

    I truly think my install was top notch and I'd really like to know if I did something to cause this failure. But really what can somebody do here that they shouldn't? Sit on the seat push the lever and it goes down. Stand up and push the lever and it comes up. Seems like a no-brainer. Although I have be doing some reading about needing to "fully" activate the lever then push down and real specific ways of working the mechanism like that. But for me that's a little to much fine motor skill for the way "I" think these should work.

    One thing I have found, infinite adjustablity IMO, overrated. My seat is usually up or down. Sometimes I like to have 1" of drop. Other than that the rest is fluff. Gravity Dropper may be the ticket here for those looking in the future, or maybe the Command Post.

    Well I'll get the new one next Monday and install it. If it has problems you'll definitely hear about it.

    I haven't read this thread yet but I still don't understand where this reputation comes from for broken pedals. I mean I understand that people obviously break them but I never have. I have one set that is 6 years old and still going strong and the other day while riding a demo bike with a much lower BB than I'm used to with my 2 year old CB EB pedals on it I hit rocks about 15 times during the ride. A couple of times hard enough to think 'that must have broken a pedal' and once so hard in a high speed rocky corner that it high sided me into space. I've never done that before. Except for a few scrapes and some deforming of the decorative plastic ring the pedals are just fine.

    I'm talking about the stainless steel rather than the Ti pedals.

    I don't have one, but would like to get one. The way this post was designed, it was designed after clamps. If any of you have any clamps that are used all the time, you will see notches form in the steel, and that is thick steel on those clamps.
    Now you look at the seat post, it is an aluminum tube with steel strips on the outside for the clamps to grab onto. I can see this wearing out over time due to the rider's weight and up and down motion of the post.
    Only time will tell how it holds up.

    Just ordered one. Now Im thinking that it would be fun to mock up a mechanical spring kit that would basically be a new end cap and a couple of bushings on either side of the spring. Any idea on dampening the return to prevent the seat launching back?? Anybody mind taking some pictures of the seatpost internals? thx.

    Thought the Kronolog looked like a good idea, but after only about 30km on it, I have noticed it slipping (about 1cm). I thought it was because I'm a big guy (100kg) but after reading this thread, sounds like same old Crank Brothers issues. I'm in a good position though, my LBS gave me the post at a good price to review for them with an intent to begin stocking them. If I didn't like it, I can let them know, get a refund and then go for another post - and they will steer clear of them. I guess you know what I'm doing?

    With 7 miles on the new Kronolog, I experienced the ~1cm of post slippage as well. I could feel the post creeping down riding in the saddle for less than one minute. Over the course of the ride, the creep grew from 4 to 10 mm as shown below.

    In fairness to Crank Bros, I'm going to check my cable adjustment to ensure I got the 2-3mm spec of play in the trigger to ensure the cable is not preloaded.

    The grease line in these images shows the before / after shots.

    Kevin, did you figure out a solution to this? I'm seeing the same thing with my ISM Adamo saddle.

    I was thinking of increasing rail diameter with some sort of metal foil, or carbon paste. Or adding some width to the plastic piece by putting some epoxy on the sides.

    Given the interop issue, crankbrothers should ship this with a slightly wider alternate plastic piece.

    In fairness to Crank Bros, I'm going to check my cable adjustment to ensure I got the 2-3mm spec of play in the trigger to ensure the cable is not preloaded.

    It looks like the cable is rubbing on the seatpost clamp. The cable neede some free movement up and down. If it catches on the clamp, it may be caught in the semi open position.

    Cable is rubbing a small amount. Doesn't appear to be interfering with the clamp operation, but I can try clocking the seat clamp a bit just to eliminate that variable.

    Had mine for quite a few weeks now and did a race on it yesterday. So far I'm pretty happy and it work's as described. Only niggle is the seat clamp coming loose on the first few rides till I loctited it and yesterday I think it may have moved slightly. Zero play, zero slop, smooth action. Happy days.

    I agree with this. I actually turned my clamp around to the back because it was touching the cable. Unfortunately, CB says that a certain amount of slippage can cause damage that makes ensuing slippage more likely so your problem may not go away.

    It would probably be useful for people to post pictures of their setups, especially if they're having problems.

    trailjunkee,

    I think this will be problem (slippage) you (and others) will have whether you get a new post from them under warranty, unless they change the design (i.e. clamping surface).
    The wearing of the aluminum clamping surface by the steel plates has already been documented by pinbike and bikeradar after couple of months of riding.

    I'm kind of POed that they put this out there w/o doing a comprehensive testing of the alu clamping surface for wear.

    This is like the 1st generation Xbox 360, and they (Xbox people) knew (they have even stated in public that there would be 100% fail) about the problem, but still put it out into the market.

    Given the interop issue, crankbrothers should ship this with a slightly wider alternate plastic piece.
    Yes, just kept tightening and loosening it till the rails of the saddle gave. the problem was the saddle. Been on a few rides and so far working wonderfully.

    Just installed mine. Works great.... But ... I can't seam to tighten my seat rails completely, still a little play and I don't want to strip the screw. Did a cursory check and everything appears to be lined up...thoughts!!?!?!

    Altered the seat post to ensure there was no chance of rubbing by the cable, and I checked the play in the trigger. It is approx 3-4 mm.



    Unfortunately, this didn't resolve my situation, so I contacted Crank Bros directly. Talked with Nick. He was really helpful and issed a return authorization for me.

    The damage is probably already done and it looks like CB is accepting responsibility for accelerated wear as a design or manufacturing flaw but the way you have it set up is how you'll want to run it when you get your new post, imo.

    Interop issue, due to poor design on CB's side. A few of us have reported this. You could shim the rails with some aluminum flashing. I'm returning mine, and buying a gravity dropper, since this post is already having issues with longevity according to others & pinkbike. The KS lev may be an option, but with the same internals as before, I'm staying away from that, too. Maybe the next generation of posts will get it right?

    Look at the Kronolog image in the Crank brother ad on the right. Cable is kinked sideways in their add too. LOL. Fail

    Funny how everything seems to work fine when dealing with "2,000 hours of testing" by CB, but falls apart after 2 months of riding (Pinkbike and Bikeradar).

    I had LEV and DOSS as 2nd choices if this post didn't' live up to expectations. But with the advertized weight and projected SRP of the DOSS, I think it might just have to be the LEV until something better comes along.

    Bikeradar have just given the post a less then glowing review, mainly based on the reliability issues - CrankBrothers Kronolog Dropper Seatpost - BikeRadar, so seems to no better than the Joplins it's replacing.
    I might as well keep saving for that Reverb.

    New Krono Here

    So I love dropper posts. I am an abnormally long legged guy so I basically need one in order to descend comfortably.

    My first post was a Joplin 4. I exchanged it for the Krono. So far I like the Krono alot but I just installed it. Came in the mail from CB today. After reading stuff online I am worried its going to suck soon but will have to wait and see. Hopefully by the time it fails, I can send it back and get it properly fixed up.

    Prolly should have waited a while to get a Krono until they have things sorted.

    I had a reverb as soon as it was released. That first gen model was a POS. I had to constantly rebleed the thing and it developed all sorts of slop. Was way worse than my Joplin. Sent it back to SRAM and they gave me a new one, which I never really rode since I sold the bike it was on. Apparently, that new Reverb is nice though.

    is there a weight limit on this?

    Mine has been super solid as well. Set up is critical. There has to be at least 3mm of free play at the lever, and you must make sure the post is "set" in to the clamping mechanism before checking the free play. I have about 15 rides, with lots of seat post usage at this point.

    Loving my Krono so far.. early days yet but it is a beautiful thing when its working. Just in case someone is interested I e-mailed Nick the other day to clarify if the bike could be held up by the saddle if the post was installed and he gave it the ok saying the locking mechanism could take a few hundred pounds.
    I think setup is a major issue here. I got my LBS to do it.

    Coming up on a month so far, and no issues whatsoever. I've been reading and keeping tabs on comments from other Kronolog owners here and on other forums/websites just in case something unique comes up - there's another thread on this forum about an owner who seems to be experiencing every single problem known to man on his post. Meanwhile there are others who are doing fine, like me.

    Here's all the tips I can remember when installing my Kronolog:

    1. When I disassembled the seatpost to install the extension limiter spacer, I made sure that all the o-rings were properly greased.

    2. Also when disassembling, I first released as much air pressure as possible from the valve, and then in between steps of the disassembly I'd push on the Schrader valve tip just to release and air that was still in there.

    3. Before mounting my saddle I wiped the side clamps, bolt, and molded center spacer with some denatured alcohol. I did use a dab of TacX compound on the bolt.

    4. When I swapped out the stock cable for some JagWire Ripcord, I removed the plastic lower cable guide and reamed out the hole slightly to ensure that the cable moved freely through it (as it should in order to release both upper and lower post clamps).

    5. I followed the suggested setup for the trigger exactly as Crank Brothers stated in the instructions - including the correct cable tension (snug to trigger spring but not compressing it), dialing out the tension adjuster a few turns, and making sure that the recommended 2-3mm of slack.

    6. Cable end was cut as close to the barrel lock/clamp thingy.

    7. My cable housing has a curve to it when exiting the mechanism area. However - like I said in #4 I reamed out the plastic lower guide for clearance due to the angle that my cable was coming out.

    IMO Setting up the Kronolog is the most important part of it; Do you just bolt hydraulic brakes on and go, without centering the calipers, bleeding the lines, and breaking in the pads? Some of the "negative" stuff I've been reading come from people who expect to just swap their old post with the new Kronolog and it should be 100% perfect out of the box. Then once they figure out what they did wrong (read: user error) they get it working as intended, but stick with the "it's not good" judgement because of their not-so-smooth beginning experience - which ended up being cause by user error.

    FYI I have had zero problems with the seat rail clamp, zero problems with the post actuation, and zero problems with air pressure. So either I'm extremely lucky, or I installed my seat post correctly.

How many times have you gotten to ride it in the last month? The reviewers started having durability problems after a couple/few months.

    I just got mine back from Crankbrothers warranty after it would not stay up. They replaced the jammers with a new set that are supposed to be a harder. The report said mine were soft and at the bottom of their tolerance. Turn around time was about a week including round trip shipping. They did a good job customer service wise.

    Only had 2 rides since repair but works again so far.

    I've got my new one and ridin it twice now. After I sent mine off I ended up with the flu and that put me down for about 2 weeks after waiting a week to get it back. So not really a lot of time yet. But this whole thing about install causing the problem seems to be a little much for me and I told them that when I called in for my RS #. The whole write up about having to ream out parts and add new cables straight out of the box,etc,etc, while I truely admire your attention to detail, seems like a ridiculous requirement for a NIB item. Also when I got mine in and installed it before I ever got on the bike I took detailed pictures of my install, from cable setup to lever setup and emailed them to Nick at CB. He said my install looked "perfect". Bad thing is it's setup exactly like the 1st one that failed after a month. My thoughts are that the jammers are not disengaging fully. Once you press the lever and they begin to disengage the post should be able to slide before they're fully disengage. So each time you're getting a little friction on the jammers either wearing them or the post. So I think we are all going to continue to see failures. The only idea I've got is to completely unweight the seat until you have completely activated the lever and then apply pressure to lower the seat. I think this is also made worse by the fact that the jammers do not acitivate at the same time. On my new one the bottom one will move first and once it's completely moved then the top one moves. I emailed CB about this and they explained that that was the expected function. To me this places a lot of stress on one jammer and over time would wear it out.

    On another note the new one that I got in will often times be very difficult to activate the lever when you try to raise the seat. I've actually had several occassions where I'll push the lever but it's like it's actually jammed in place and won't activate and I've ended up in an awkward position with the seat down when I needed to start climbing. Haven't contacted them about it because I figure as it wears it will get easier to activate and I really expect it to fail again.

    Funny thing is I explicitly asked Nick to contact me about what kind of wear they found when they got my old post back because if it's something I'm doing I want to make sure I change. But I haven't heard anything back. This tells me either they are getting so many returns they have forgotten about my request or the post failed due to a flaw. I would expect that they would want me to do things differently if I'm doing something to cause this. I really think we've probably all ended up with a bad design. In hindsight I wish that I had ordered the Giant post but oh well I guess I'm in it for the long haul now. I knew about CB's reputation but I really blew it off as internet talk. So now I'm just dealin with it. I'm kind of looking at it in terms of Lemon Law though. If this thing has to go back for a third time I'm probably going to demand a refund, Probably get some reason that they won't refund it but I'll probably raise a real stink about it and really try to push for it. If not I guess it's going in the fire. If it continues to fail I would never think of selling/giving it to someone else.

    So my unit doesn't hold air pressure because I installed it wrong? Interesting theory.

    Crankbrothers is local to me and I know most of the people who test their stuff and they just don't ride enough (hard) to properly Suss things out. Same deal with their wheels.

    I said: "...some of the "negative" stuff... then once they figure out what they did wrong... which ended up being caused by user error." Keyword: some. I have no idea about your particular unit - but there were a lot of others who's experiences I've read that were, in fact, user error. It was more of a general statement referring to what I happened to read elsewhere, sorry about that - I didn't imply that ALL problems were user errors.

    On the other hand, I also agree with a previous post in that I also doubt that user error is a valid explanation for all of those mentioned reviews from Bikeradar, etc. Maybe I should just chalk it up to being "one of the lucky ones' then?

    If a particular product (not saying this one) has a 50% failure rate, then obviously 50% don't fail. Not too impressive though... We have heard enough issues with this post to know that there are problems. Chalking this up to user error, even if 100% true (which it isn't) will equal doom for this product, at least until significant changes are made.

    Oh well, mine seems to be working and handling usage fine so far.

    Here's something interesting: I was experimenting with the air pressure today, tried lower air pressure and I noticed that if you drop the seat post down while sitting on it, the post seal will go beyond the flat areas of the stanchion and and up to the curved area at the very upper part of the stanchion (below the saddle clamp area). the post will get stuck because the upper lock lever wouldn't release when you click the trigger - I had to pull up on the saddle slightly before it got unstuck.

    However, with a higher air pressure (suited more to my weight maybe?) there would be no sticking at the bottom when the post was lowered. The seatpost would work as expected. This might explain why some people are having sticking problems when the post is lowered; either too much weight or not enough air pressure in the post? What do you think?

    X2- I've ran CB pedals for years and never had problems with them (other than wearing out the spring). But riding 5-7 days a week 12-25 miles a day that was okay.

    Haven't had any problems with my Joplin 4 yet too (knock on wood)

    10 rides on my Kronolog with no problems whatsoever. No slippage or air loss to report. Keeping her firm at 165 psi.

    On the bottom cap it says "Max 100psi" - not that anyone should run it that high to begin with.

    wow, thats what happens when I post late night. 65 psi, not 165. 165 would probably shoot me into space.

    Like someone else has said on here, they should have used a coil spring instead of air and it would have been perfect. The locking mechanism is the genius in the design, who cares about an air spring. Make it a real spring and it would be so much more reliable, it'd be like a GD with looks - imagine that. Captain Hindsight signing off .
    Not only more reliable, but probably cheaper. I probably would have bumped the weight up a bit. But then again, most of us aren't XC racers.

    Raine: My post hasn't stuck at the bottom. They just sent me a new post and we'll see how this one works once I get a chance to install it and try it out. Hoping for the best...

    I read the "sticking" on another forum... but it seems to only happen if the air pressure is set too low for the rider's weight. Just thought I'd mention it here too

    About 30 hours on mine. Works fine.
    I'm about 210 lbs. and am using it about 3-4 times per ride, mostly for easy get-ons.
    Proper set up is crucial but not too difficult.
    So far, happy with the purchase.

    I've been on my Kronolog (2nd) for about 1 1/2 months now and spent a great deal of time riding some intense, technical trails (Moab - Magnificent 7, Porcupine, Portal...as well as smooth fast in Fruita/Loma/Rabbit Valley/Eagle and now with Mountain terrain drying out, Summit County, CO. On any given ride I'll adjust my seatpost an infinite amount of times dependent on terrain but I use my dropper as much as I feather my gears to have optimal riding stance for any terrain. Hopefully that gives you an idea of my riding style so you can base my review of the Kronolog accordingly. I purchased the first one the day it arrived at the Poison Spider shop (I was intrigued and awaiting the product and my Reverb was sized a 30.9 seatpost from a previous bike which doesn't fit my Ibis- riding the above trails without a dropper would suck). It was new to the mech team so we had a few trials with install but overall it came together just fine. I'm installed on an Ibis Mojo HD and running through the housing routing across top tube (although I have loosened as well as removed from cable routing also to test performance) Anyhow, after two days of trail use through big drops, technical descents, and hard riding I started to experience about 5mm of drop when riding. A firm push could produce the same results therefore I started to adjust play in routing and slack in cable...no changes. On day three about halfway through a 20mile descent the Kronolog failed completely and I was hitting rock bottom with any pressure being applied to seat. I returned to shop and they were kind enough to take the shop managers new post and give it to me to replace the prior post. Hoping this was a "lemon" I accepted the new post, installed and have been on this one now for about 30days. Approximately 250 miles maybe more, less large drops but still very technical and riding the seatpost has once again begun to slowly slip about 5mm down with climbing pressure during ascents. I have been to two shops, played with all cable routing, pressure and done appropriate maintenance. Evidently this isn't common (per crank brothers and I can send back to them for replacement - but 2 lemons?) Anyhow, they told one of our local mechanics they are increasing the depth of the slits in the post (where the levers grip the post up and down locking the mechanism and haven't seen this problem more than 2-3 times but we'll see. Overall, yes it is a damn pretty seatdropper and the cable routing is great comparitively speaking to the reverb but overall performance isn't there for me! Maybe I was unlucky and got the lemons but I'm hoping the improved versions will eliminate the problem. That's my two cents, hope it helps your buying decisions in the future. I'll keep you posted with any changes or performance in the 3rd model I receive! I do hope it functions well because nothing sucks more than small annoyances or mechanical failures on big rides!

    Mine has started to slip 3 or 4 mm from the fully extended position. I don't have to sit on it to make is slip, I can push it down with my hand.

    Not sure how many hours I have. Maybe 20-30? I'm pretty sure I set it up correctly, using the cable/lever/post assembly as it was out of the box and making sure nothing was preventing the cable from moving freely.

    At this point, it's not affecting my position or enjoyment much but I'll keep an eye on it and on what CB is doing to remedy the issue. I'm really enjoying having a dropper post despite the reliability concerns.

    The new MTBActon has a review of the post and they liked it quite a lot in the short time they road it, but still needed to test it for long term reliability. They said the weight was at 3/4 lb more than a carbon post it replaced. That's getting better but I wish they or others would start using carbon fiber for as much as they can on drop posts to get the weight down even more. That is the only thing that is keeping me from trying one. All my main bikes are pretty heavy long travel so the thought of adding almost another pound that I can easily avoid stops the purchase. A metal spring is a bad idea even if it was Ti, which would also raise the price.

    I guess simplicity helps with reliability but it seems like the infinity adjustability would be a bit of a pain if you wanted a consistent midway cornering height. 3 stage make more sense.

    One of these days...
    No it never stops hurting, but if you keep at it you can go faster.

    Well that was quick. On the second ride it now slips a little less than 2mm. So the second post is not holding up either, though this time it does hold air, at least so far...

    The post will settle about 2mm as the clamps pivot into the locked position. Make sure you check cable tension at this point, as this settling takes up a bit of free play at the lever.

    Letter to CB

    Hello,

    As an avid fan of dropper posts since my first acquaintance with them via the Joplin 3, I was eagerly anticipating the delivery of my new Kronolog. The Joplin was a fantastic idea, reasonably executed, but the reliability was non-existent. It lasted all of 3 weeks before leaking fluid all over my bottom bracket whilst sagging horrendously. I then replaced the seals and it lasted all of a further 2 weeks, where-after I simply binned it. As a customer I was frustrated but open to exploring other ideas.

    I was about to place an order for a Gravity Dropper, and then I saw the promo-hype for your new Kronolog. Man was I taken with it! It looked fantastic, and if the design was as good as you claimed, then it would be absolutely primo! I read every review, watched every video (repeatedly), salivating at the thought of having my bike handle like a large BMX once again!

    So I ordered one and eagerly awaited its arrival. My initial impressions were that the presentation was top notch and the finish superb. I installed the post, and one sleeplessly anticipatory night later was out on the trail. What an absolute blast! It operated as expected; was rock solid, and absolutely no saddle movement! WOW! I could only do a quick 10 miles XC ride (4 month old kids place significant time-constraints on one!), and I was well, well impressed.

    Until today. Preparing my bike for my next ride tomorrow, I sat on the saddle and the post sagged ever so slightly. Checking the post, when right at the top, if reasonable weight is placed on the post, it drops about 10mm, then locks. I could live with this, but I can feel the metal grinding against metal during this movement, so I'm not sure how long this will now last. I'm very disappointed that the post is seemingly starting to fail, and I've ridden it for less than an hour. Which is about 1999 hours short of the 2000 hours you guys tested, right?

    In the near future I shall be ordering a Gravity Dropper, and selling my Kronolog. I cannot abide a component on my bike that may fail, particularly when I am 20 miles from home. I will never, never, never (did i get the that right? no, one more never ever fit another CB product to my bike. At some point you're likely to go bankrupt and I suggest that your marketing personnel should work for Apple or BMW (or any well known brand that requires marketing/PR genius). I suggest that your engineers find gainful employment as anything other than engineers.

    Regards, your ex-customer,

    Dean

    What a freakin lemon, I actually feel bad for Crankbros, this was their chance to shine. I can't believe they didn't do more testing. It's ridiculous that all of the production units are failing immediately. Somebody over there dropped the ball big time.

    Hopefully they can manage to fix the issues, but they should of done this before releasing it.

    Maybe the next batch will be improved and reliable like the 2012>2011 reverbs. Seems to be a nice unit if it didn't fail.

    Thanks Scot. My first post wouldn't hold air for more than 1 day. In addition it sank 2mm, then 3, then 4, then 5. You get the idea. The cable tension was checked, housing had free movement as needed etc. This one holds air so far, but has started the dreaded sinking.

    Not a good start!

    I think if they used steel strips for the clamped surface that it would hold better than soft aluminum.
    Look at the Lefty, it has steel strips for the needle bearings to ride on and that lasts pretty long.

    This certainly doesn't look good. If that's what they told the mechanic it was a flat out lie. There are more people in this thread alone with this exact problem so I can't imagine how many are actually out there with this problem. Seems like it's probably a case of CYA so it looks like they've probably got a major issue on there hands. It's too bad. I pretty much like mine, when it works.

    Got my Krono back from CB on Friday. Saturday's test ride of 8 miles with several extensions / retractions showed operation as expected. Seat never settled in past ~1mm of full extension.

    So far, so good. Looks like my issue has been resolved.
