    It does come to a complete stop. It's just that as/when I tighten it towards the end, it creaks a bit then eventually stops. It doesn't creak at all with the first 3/4 of the tightening...only at the VERY end. Threads look good, and I haven't seen any metal shavings.

    OK, you did not say that in your original message. If the bolt is feeling resistance as you tighten it, then maybe it wasn't quite situated on the spindle completely to start with and it is being pulled on by the tightening of the bolt. If the bolt is coming loose by the end of your right, you may not be tightening it enough. Check the torque with a wrench if you have one, or just try a bit harder to tighten it up next time. Hopefully, it should stay tight for you.

    2004 Lefty Max TPC 130mm repairs

    Hello all. I have a Lefty Max TPC 130mm off a 2004 Jekyll 1000 and want to replace the rebound shaft seal. Am I correct in thinking that I dont have to pull the inner and outer legs apart from each other, therefore avoiding having to wrestle the bearings back in? Also, on my last ride I went to adjust the rebound adjuster and it no longer has its stop positions at each end of the adjustment range. The adjuster knob is turning the rebound shaft as I can alter the rebound speed, but the knob can turn infinitely in either direction and does not stop at the maximum and minimum adjustment points. It definitely worked properly a couple of days before. Does anyone know what may be causing this?

    Thankyou for your help

    2007 Lefty Max Titanium, TPC + , SPV 130mm

    Hey guys just a question on my 2007 Lefty Ti, TPC max SPV. I am looking for a Firm titanium spring.

    I went to my dealer and he got me a 140mm exfirm steel spring with 5 wt oil vs 2.5 wt which is called for in my manual because thats what Cannondale sent him, they said they dont have any parts for the Lefty. I measured the spring, its 245mm vice 241mm which is called for in my manual for the extra firm steel spring, designated for the 130mm travel fork.

    My problem is can I use the 140mm lefty max spring in my 130 mm travel lefty by shortening the preload spacer to keep the overall total spring length and preload max measurement....


    my dealer says that the fork was made by manitou and they went out of business so Cannondale cannot get the parts any more...otherwise he would have sent me the firm ti spring.

    what can I do ? Im just getting too much static sag with the stock medium ti spring the bike came with.

    Thanks

    Patrick, Montana

    Lefty 110SL Removal

    I have a 2009 Rush Carbon. Recently the Lefty 110 SL started to wobble side to side at the end of a ride. I'm planning to remove the shock and send it to Mendon for a rebuild, but I'm unsure how to safely remove it from the frame.

    I've found several references and great instructions, but all of them show the process of removing the steerer tube after removing the stem. Mine has an integrated stem so I son't see how that would work. Not sure if I need a specialized tool for this setup or if it is something simple I'm not seeing.

    I don't want to damage the carbon in any way so any tips or techniques would be greatly appreciated!

    I'm guessing you'll probably need the KT020 tool to safely remove the steerer

    Thanks for the notes, but this system is different than mine. This method requires removing the stem, then tpping out the steerer. My rig has the OPI (One Piece Integration) Stem/Steerer which doesn't allow stem removal. I'm guessing it has to be tapped out from the bottom, but there is no lip on the steerer to really work with.

    I'm wondering if the same tool is used, but the OPI is tapped out from the bottom rather than from the top. Has anyone done this with the OPI Stem/Steerer?

    The Eight-aid link shows two menu options for removal and installation of the OPI.

    Did you look at them, or just the top link?

    Brilliant!

    Found the expanded menu with the OPI window - Indeed the K2020 is used to tap out the steerer from the bottom. I'm ordering one now!

    Thanks for the input everyone. I'm bummed to be off the bike during prime season. This should get things moving!

    If you have an OPI stem do you still need that tool??
    it seems from the eighty -aid guide, that all you do to remove the stem is to just unscrew it
    The older stems only require the KT020 tool?

    Thanks for all of the help everyone. I managed to get the unit removed and it is at the shop. Looks like bearing migration - A few parts and a few days and we're back in business. Thanks to this thread I now know how to perform my own bearing resets so this should not be an issue again. Thanks again!

    Cartridge oil seal

    What is the consequence of the cartridge seal not being installed? Item 6 in the attached image.

    Installing the cartridge without this seal it still holds air...

    This size o-ring is hard to find without buying the whole seal kit. I change my bearing grease regulary and having seveal of these seals on hand would be nice.

    Anyone know of a source for 18.77mm x 1.78mm o-rings?

    Charkear, the only purpose of that o-ring is to hold the washer (item #38) in place during installation. They fall apart very easily so I don't use it on mine.

    Thanks, it looked superfluous. It is nice to have something hold this metal ring on. When I installed the cartridge the ring got out of place and was making a grinding sound on the upper for tube.. No damage done though.

    You probably need a service. Your O-rings cant hold hold the pressure properly, so if you do it yourself, I would quess a new O-ring kit.

    Lefty Speed Carbon XLR and little play

    Hi all,
    I've a Lefty Speed Carbon XLR 2011.
    Recently I've noticed of a little play when the fork is not locked out: if I push applying very little force, the fork doesn't begin to "work" (compress air) immediatly but there is a little "gap", like if the damper is not pushing immediatly on air chamber.
    If I push with more force, the fork begins to work normally, and it works well. The air pressure is ok and is mantained correctly.
    When the lockout is triggered, the fork seems to mantain this play, but is very little (for now), like 1mm or less.
    One month ago removing air and re-inflating the fork immediatly eliminates this problem. Now this "workaround" won't work anymore.

    Is this behaviour normal ? What could be the cause ? What could I try to check ?

    Thanks

    White "blk" on bottom of lefty max 140mm

    Question. I have a Lefty MAX 140 and have recently realized that the letters BLK are written on the bottom of the Lefty (on wheel hub). I am assuming this means black spring?

    Also there is no valve on the bottom of my MAX 140....does that mean it's a TPC? The spring chart is different with the SPV vs. TPC.

    Trying to dial it in for a 190 lbs 6'1" WW......right now the front end drops quick on my when braking.

    Any tips?

    if there is no blue knob on the bottom then you have a FFD not a TPC, the spring chart for the FFD and TPC are the same, think the black spring is good for your weight.

    when was the fork last rebuilt, maybe your quad seal is starting to leak, look under the boot and see if the grease is starting to breakdown.

    you can dial up the preload of your spring too.

    I have a TPC and it gets "softer" when it needs servicing.

    Lots of questions, but nobodies answering them. Ok here's one. I love my lefty but don't love the flexy swingarm of my prophet. Looking at building a stout 4bar all mountain bike that fits a lefty. Maybe a banshe rune. In order to fit do I need:

    1.5 head tube
    Lefty headset (not any 1.5 headset)
    A specific head tube length of 121mm?

    Anyone Confirm this? Thx

    A 1.5 Head tube WOULD be helpful, no adapter necessary. But if you go with a frame with a 1 & 1/8 heat tube there all kinds of adapters. Cannondale has an official adapter: Cannondale Lefty Steerer Tube Conversion Kit to 1 1/8" Part Number KH075
    here's a link to one on cannondaleexperts

    here's a video talking about (among other things) the adapter and the different crown heights the newer lefty's come in. I know you want to use the lefty you have so look for a frame that it will fit.

    If your looking to get rid of your Prophet, PM me. I'd LOVE to get my hands on one of these. Right now I have a 2006 rush 4 but my hart is relay set on a Prophet.

    2011 XLR 100mm

    Got a problem with the rebound adjust. Since it was new the rebound knob was very hard to turn. With as much force as I could muster with bare hands I could adjust the knob and got it set where the rebound was good.

    I reset the needle bearings for the first time and once I loosened the top cap a little I could move the knob with ease. I reset the bearings with no problem but when I reassembled the remote lockout and rebound adjuster the adjuster knob just keeps turning with out stopping. I have look at it every way I can but it looks like the shaft of the lockout/remote fits properly. Once I tighten the top cap the rebound knob is now impossible to move by hand.

    Lefty performs fine. So what is broken?

    Hi!

    I have a Lefty Max fork TPC 140 of 2005, and I want to do the oil change following the instruction manual, but I can't loosen the lower screw (22mm key) because I think that there is an elastic pin (see the photo).

    I wonder if this is normal and how can I do to remove the pin. The fork was repared for Eighty-aid service.

    Thanks a lot, and sorry for my english!!

    Lefty Max 140 SPV Bearing question (Too Tight)

    I recently had my Lefty max rebuilt by a known lefty service center. It was in rough shape prior as I bought it used. The center replaced the bearings, and rebuilt the rebound circuit as it was badly damaged. The SPV functions, as does the rebound now. My problem is that the fork is really tight. It feels like the bearings are really tight between the races and there is too much friction to allow them to roll smoothly. Its not gritty just really tight. There is plenty of grease on the races. I was told since the bearings are new it would be tight until i put a few miles on it and everything settled in place. Ive got probably 10 miles on the fork now and its still just as tight. It is sprung correctly so that is not the issue. Feels bearing related. Any ideas??

    I've got a DLR Lefty 26er fork with clamp on crowns, which I want to convert to fit a 29er with a 1.125" head tube.
    According to Project 321, I need the Clamp-On Lefty Adapter, complete with new crowns, at $200.
    Is there a good reason why I can't use a standard Project 321 adapter at $90, or the Dr Cannondale adapter at €72, which both work out at about £60.

    At last, I can say that the pin does'nt block the screw (they had to put it only in some series), but I can tell you is really strong ...

    I have now opened and now I have to do all the maintenance inside ...

    Carbon SL 110 replacement damper part number?

    I had the same problem as Radditized below. I got the damper serviced and now it works as it should but the shop said I still do need a new damper.

    question is what is the part number for the carbon SL110 fork damper?

    Thanks

    I did a bearing reset according to your reset guide (very nice, thanks ).
    And now a few weeks later, the lockout has a kind of sag, before it really locks completely. It is about 10-15 mm before it locks.

    I have an alu lefty which is newly serviced, and feels really nice compared to my carbon lefty. And it locks immediatly, without the sag.
    Im afraid I have dont something wrong perhaps, while resetting til bearings.

    I went to my LBS and he said with just testing the fork, that I properly needed a new cartridge. But I would really like to save the 300 dollars it would cost me.

    Any ideas?

    Thanks

    I never figured it out


    But I have another problem. My Lefty XLR 29er has a klonk sound when its locked. It probably needs a service also, but could a mere service solve the problem, os is there something else to this klonk sound?


    Cheers

    I took my fork to be serviced and got it fixed. Left 29er DLR. It needed new oil, thus the squishy feeling even when locked out. I also had the klonk sound when locked out...actual movement in the top assembly of the fork when you pulled up on it...about 5 mm of movement. Bad. I thought the fork was f'd. Turns out, it was just loose and in an easy place to fix. My fork has a red rebound knob on the top, with a small set screw holding it on. Remove the set screw and take off the red cap. Under there is a protruding spindle, with a small 10mm nut on it. Careful, it's an aluminum nut, so easy to strip. Mine was loose so the entire assembly would rock up and down. Tightened that down, and BAM...no more movement. Replace rebound knob and set screw and all is good in Lefty land. Hope that helps.

    Mine doesnt have that 10 mm screw, I remember it did have it on my older 2008 Carbon SL (110 mm 26")

    But I want to give my 2011 Lefty carbon XLR (90 mm) a service, but a service kit is a bit of a reach. I have used it a lot since june 2011. Can I just change the oil and leave it at that? Or would I need a full service kit, with new o-rings etc. This is first service since new of june 2011.

    Because then I would just change oil tommorrow, and change o-rings at next service. I know it depends on what state the o-rings are in, but does any have any experience with first service leftys from about 8 months use (ca. 5000-7000 km)

    A fast response is VERY much apriciated, thanks

    Cheers

    i need advice...

    My PBR Lefty travel is awfully short~
    Is it because of the air escaping or something else?

    Is it short due to it not being able to be fully extended or because it tops out before hitting full compression? From what I gather, the former (not fully extended) could be due to lack of air pressure (check your PSI! Don't ride it if under 50 PSI!). Some pumps are problematic getting a shock pumped up due to having a hard time getting the Schrader valve opened up.

    The second sounds like it could be a needle bearing migration problem that would need a bearing reset.

    Of course, MendonCycleSmith should probably be advising you, not me.

    help, my Lynskey frame broke and I decided to replace it with their lefty specific frame. I bought a Lefty Speed Carbon XLR 2011 (expensive) I rode it ~ 140 miles and I took it to my shop because of a rear ss hub issue. Anyway my favorite mechanic pushed down the fork and when it came back up there is a louder thump. I left it with them and it is apart. Any idea what this could be? I may have noticed it when I pooped the front wheel up to get the front wheel over the curve. Thanks in advance for any help.

    Lefty Carbon ELO disassembly: help needed

    Hi everybody!

    I've got a Lefty Carbon ELO with Ti spindle.
    The issue is that the motor buzzes, but no lockout happens.
    Seems like the motor itself is OK, and the problem lies in its relationship with the shaft.

    I'm trying to disassemble it, but it now seems that I need some external help with that.
    What is the disassembly sequence for Lefty Carbon ELO, and what does the special tool that's required to detach the damping cartridge look like?
    The part to be unscrewed suggests that the key should have 4 pins, just as HDTL146, but longer, and I wonder how can it be put in there, for there is not as much space for it as in the modern versions.

    I have read many success stories of ELO disassembly/repair/replacement here, but no clear instructions, unfortunately.
    So I ask you for assistance.

    Thanks!

I measured the spring, its 245mm vice 241mm which is called for in my manual for the extra firm steel spring, designated for the 130mm travel fork.

    My problem is can I use the 140mm lefty max spring in my 130 mm travel lefty by shortening the preload spacer to keep the overall total spring length and preload max measurement....


    my dealer says that the fork was made by manitou and they went out of business so Cannondale cannot get the parts any more...otherwise he would have sent me the firm ti spring.

    what can I do ? Im just getting too much static sag with the stock medium ti spring the bike came with.

    Thanks

    Hi, I have a max 130 tpc with the black spring. Way to stiff for me. I need the blue. If you are wanting to trade or sell me your blue it would be great.

    Convert coil Max RLC to 29"

    Is it possible to convert a 2010 Lefty Max Carbon with Fox RLC internals and coil spring to 29-er by limiting the travel? And if so, what travel will I get? I have a fork I am going to sell, and most of the people intererested wonder if it can be 29-erized.

    Thanks in advance.

    You would need to change the whole damper which isn't hard to do if you have the correct tools. I would gladly swap out with you.

    How hard is it to change the Battery on a 2001 ELO Lefty? Is this something a total NOOB could do or should i have a bike shop do it? Sorry if it is a NOOB question.

    Thanks in advance,

    check the manual on cannondale.com on support zone , lefty section

    Cannondale Factory Rebuild

    I am being told that Cannondale will no longer service my 2005 Carbon 140.
    Is this true and if so what are my other options?

    thanks

    guys, need your support... I have Super Castle tool (like this: Cannondale Super Castle Lefty + Headshok Cartridge Removal Tool - KH031 - CannondaleExperts.com ) and Lefty 130 PBR Carbon. Today I have tried to remove damper cartridge from my lefty but I wasn't able to do this, because this tool can't reach the damper itself, it looks like the shaft of the damper is longer then the tool and the rebound not does not let the tool reach the damper.
    Hope I described the problem so as you can understand

    Yes, I have released all the air from the fork and pushed all the way up the fork. As I wrote it looks like the shaft of the damper is longer then the tool is.

    Perhaps I should take out the rebound knob to fit the super castle tool? Should I?

    A quick question to anyone with experience. I need to change my lefty air filter boot. Got a small nic in it.

    Is it best to remove the main boot or is there a way to slip the filter boot over or under the main boot?

    no way, you'll need to disassemble the lefty.

    Thanks Vasiliyg

    So you are saying even with the boot removed, the filter boot will not stretch over the brake mounts?

    I won't need to replace the actual filter (sponge), only the rubber outer.

    you can try to do the same with the filter cover:
    boot change - YouTube

    personally I haven't try, of course if you take apart the lefty it will be easiest part

    Does anyone know the A/C lengths of say 26" Lefty vs. 29" Lefty? I have a Flash 29er and thinking of doing a 650b Rush and wanted to know how much geo would change if I used the Lefty of my Flash 29er. Thanks!

    There are 3 A-to-C lengths for the 3 types of modern Lefty's.

    470mm = 100mm (26) / 70mm (29) - aka Lefty "Speed"
    490mm = 120mm (26) / 90mm (29) - aka Lefty "Ultra"
    510mm = 140mm (26) / 110mm (29) - aka Lefty "Max"

    Those numbers are for PBR/XLR setups...

    So there really is no such thing as a 29er specific Lefty since all 3 can be (and are) used on 29er bikes. I think the Flashes come with Ultras set to 90mm. I think the Rushes came with 110mm DLR2 Leftys, so the Ultra will be 10mm taller with the same sized wheel. The 650b front wheel will make the front even taller.

    I'm a big 650b fanatic so I say definitely give it a shot. However, you might want to keep your eyes open for a 100mm Lefty Speed if you feel the Ultra makes the front end too slack.

    Thanks for the response! I'm really interested in the 650b. Do you have any experience running the Lefty Ultra on a Rush?

    I have my eyes on a Lefty Speed on eBay but as you know even used ones aren't cheap. Using the one I have on my Flash would save money but I do worry about messing with the geo of the Rush (which I like a lot).

    this looks like the place.
    I am building a 2007 Scalpel, size XL, from the frame up.
    I need to findout the size of the headstock, which brake sets are best to go with,
    rims, tires, etc.
    Is it worth it to spend the cash on the Lefty Fork, or would a regular Rock Shox fork work as well?

    I'm 6'5" and 225, and want to make sure i give myself enough room to use my legs, so the best size for the cranks, rims and all would be great advice.

    The minute details, for headstock, forks . . . it's all going to be important to hear

    Thanks for your help, looking forward to building this bike getting out there!

    You could have just spammed the test forum with 5 or 10 posts which is exactly for getting your post count up so you can start a thread on your own...

    Just saying.

    Good luck in getting the Scalpel together. Post pictures when it's done.

    a what's what of Lefty's - DLR, XLR, PBR, OPI, etc?

    Hey all.
    I'm trying to get a grasp of the various models & features of Lefty forks. Can anyone recommend a blog or website that explains the various models of Lefty forks (or chopsticks)?

    Thanks.

    650b for 2009 110mm lefty rlc

    Hello all,
    Sorry to revive an old thread, but looking for some help on fitting a 650b wheel to a 2009 lefty rlc 110mm. I've searched a bit on my own, but haven't found any definitive answers. So:
    1. Will a 650B wheel work in this fork without any spacers etc?
    2. If not, is there any spacers available or has anybody made any that work well?
    thanks!!

    Anyone has picture of the "recommended" rerouting for the brake cable underneath the down tube.
    I find that the out of the box setting (well the one set by my shop at least) is weird and makes the hose way too long and grinding on the frame.
    I have seen people talking about rerouting it underneath the frame but i never could get a glance at where exactly they would put it through.
    I'm thinking of buying Ragley Triple Cable Guide Kit to fit and would really like if someone could post picture of their "better" routing.
    Thanks,
    JF

    Lefty question: toolset to service c-dale with Lefty on my own

    Hey guys, I'm taking my c-dale flash carbon to Afghanistan where I'm stationed at the moment. Of course, the local service shops won't have great ideas what to do with my sexy bike if something goes wrong. And that's fine, I will learn how to service it myself, but here is the question: what tools would you recommend to buy to be ready for anything?

    Thanks so much!

    I'm new on here and planing to join the 'Lefty club'. I'm hoping that a few you knowlegable lefty heads are up for a game of 'what's the year'

    I'm trying to figure out what year this lefty speed is: (edit I can't post a link to the eBay listing so heres the title: (New) Cannondale Lefty Speed Fork Black (100mm)


    I have contacted the seller and he is trying to find any records he might have but I though I might burn the candle from both ends and see if one of you guys might know what year its from.

    The seller has included some photos and the serial number DLR0521742 (Could it be an 05 from the serial? I think that would be too easy though . . . . )

    decided to post my question here so as not to create a new thread:
    I own a 2009 Lefty Max 130 PBR and after numerous bearing resets outer collar started to wear out and I decided to replace it with a new one. Manual says that I need KH045/046 but I can't find it anywhere. Can you guys advise if I can use one of these as a replacement for KH045: Levers, Knobs, Collars, + Adjustments - CannondaleExperts.com

    If I were looking for a new upper collar for my Lefty PBR Max from 2009 (on my Rize 3), I would probably start with the KH064 here: Cannondale Lefty Upper Collar for PBR OPI Alloy Structure - KH064 - CannondaleExperts.com

    I guess that C'dale probably updated the part. I hope it still fits the older model.

    forgot to mention that I have a Carbon version of Max 130.
    I wonder why C'dale differ collars between alloy and carbon lefties? they both mount on alloy thread?

    Oh, then try the KH063 instead:
    Cannondale Lefty Upper Collar for PBR Carbon Structure - KH063 - CannondaleExperts.com

    I would send MendonCycleSmith a PM to see if he agrees. He's the expert. I just pretend.

    DRSpalding, thanks for support )

    can somebody else confirm that this would be the right choice? because it will take about three weeks to deliver it to my place and I will be very disappointed if when the collar will finally arrive it won't fit my lefty

    My Lefty 130 MAX released and went 90 degrees when popping up over a small rock on a climb today.
    I am very thank-ful this happened on a climb, for if this had happened on the downhill I would have been toast.
    The fork was fully tuned just 3 months ago.
    The LBS says they have never seen the like before, how about any of you?
    Thanks.

    So I've got a question about swapping brakes on my 09 Caffeine 29er single speed. Just bought it a few days ago, and the brakes don't seem powerful at all. I'm 220 lbs, and the brakes are the Avid Elixir 3's. I can barely lock up the rear - so not nearly strong enough, and the front - even when mashed on, only brings me to a stop after rolling a few feet. I'd like it to be strong enough to throw me over the bars if I'm not careful.

    I've read some reviews that these brakes aren't terribly powerful. And I really need some good stopping power for me and the 29er. What's the best solution here? Upgrade the brakes? New bigger rotors? I've got a 185 on the front, 160 on the rear. And if I do upgrade to a bigger rotor, which I may do anyways - even if I upgrade brakes, what will I need? Where would I get spacers, etc.

    Any help would be awesome!

    Correction - They're not Elixir 3's they're Juicy 3's.

    I bought Flash Cannondale F3 2012, for the assessment of your car. Thanks

    I just like my old Carbon Lefty so much...
    I'm also wondering the same. I have an alloy Speed DLR2, is it possible to stick in the a PBR 120/140 damper ( red ) with some change on the upper seals ?

    Can anybody tell me whether travel on a PBR'd fork is adjustable, or just changeable from 140 to 110 and back? I'm looking at converting an alloy Lefty Max to PBR, then adding 321 clamps. I figure with a short headtube, I may be able to get some travel back vs. a fork with fixed clamps, as I can raise the adjustable clamps up as high as they'll go.

    it is not adjustable, you can only install spacers if you need to reduce travel of the fork.

    Can I reduce it to, say 120mm instead of 110 though?

    can I run the OPI stem with a Lefty in a 44mm headtube? as long as I use the Si headset cups and have a headtube of 122mm it's good, right?

    Just wanted to give kudos to mendoncyclesmith for their quick service! I sent my Lefty DLR to Craig for an overhaul. Had it back within a week and it is butter smooth.

    Thanks Craig

    Lefty Brake Mount adapter 160 to 180mm

    I'm wanting to increase braking power on my Tallboy with Lefty which is a PBR 130Max and a 160mm rotor front and rear. I'm using XTR 975 calipers with M06 Metal brake pads, but just don't have enough stopping power at times. Wanted to increase the front rotor size to 180mm, but wasn't sure on the caliper adapter needed.

    From what I can tell, I think I need the Cannondale KP176 adapter, but wanted to confirm with you guys? The brake mount bolts fasten from the side, unlike vertical as on the newer Scalpels.

    I'm looking for 100mm 29er axle to crown length and rake.
    There's a lot of different numbers floating around, but I'm not sure what to trust. Is A to C 490mm?

    Lefty ELO seals/replacements

    Hi, just a quick one after breaking about every single bit of my ELO working it all out, ive managed to loose from the inner damper shaft, one of the two little black nylon split washers. These sit on the area where the brass plunger and motor is housed. can these be replaced with a o ring rubber seal? and what do they do?

    I got a new seal set from Leisure lakes did all the o rings that were like for like but have loads left so wondered if any of these are upgraded or replacement for the split washers

    Thanks

    rlc lefty fat tire?

    I have a 110mm 2009 lefty rlc. I understand you can't put travel limiters on it, and was wondering if a 26" with fat tire/rim would have enough clearance.
    Thanks!
