    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.
