    Good idea!

    And rather than just put the link, I would name them or describe what each link is. Like this:

    Lefty swap in Perth Australia

    I have a F900 with the original lefty (2000). Love it and will not get rid of it. My Lefty is getting very tired and to service it in Perth, it has to be removed from the bike and shipped to Sydney (min $300 for a service). I have done it twice already.
    I would like to replace the old lefty with Lefty Max Fork TPC or Lefty Jake Fork TPC.

    I can't get any help from the local shops with informationon whether the forks can be swapped straight across or which new fork is compatible with my old machine.

    Purchasing a new Cannondale in Perth is crazy. I can get on a flight to LA return, buy the same bike for less thn the bikes here.

    Any help would be appreciated.

    Hi Chaps, I have a Rush 2 Carbon 2007 with a 110 DLR shock. The shock has always been really bad on small bumps, bridalways a couple of days after a wet patch is like handling a jackhammer. Whilst my hardtail's R-Seven's just soak things up. Is there a way to set the spring softer on the 110 or do I have to have another spring installed? No idea what spring I have. Had the top cap off to see if resetting the the shock would help and that did not expose the spring unfortunately... Any help appreciated!

    Hi,
    sorry, but I am looking for the pure technical diagrams and "pseudo" CAD drawings of the Leftys (in particular the 110mm XC models for 26er and the ones for 29er).
    In particular I am very much interested in height from axle below head set, above, diameter of the forks, etc. for a custom drawing/ custom build.
    Anyone aware where PDFs like that would be available?
    Thanks!!!

    It'll never not be an "issue", it's part and parcel with the design. The Max, and all the DLR2's feature super easy rider doable resets. Earlier forks weren't so simple.

    How do you set the sag on a lefty? I know with a conventional fork, I use a zip tie and can measure it that way, but with a lefty you can't do it. Any info would be helpful.

    I put the bike straight against a wall, mark the wall with a pencil, at the top of the grip, unloaded, then with me on the bike...

    You can put a strip of masking tape on the wall before if you don't want to put marks on the wall. Depends if you do it in the garage, basement or in the living room.

    Looking to change my brakes on my 08 Caffeine 29er 2. Want to go with the Avid BB7 mechanical disk brakes. Will I have any issues with the install? Is it a direct replacement or do I need to buy a special mounting bracket? Any info would be great. Thanks.

    I rebuilt my dampening cartridge for my Lefty 29'er Carbon w/DLR yesterday. The lockout stopped working and the dampening felt wrong. Turns out a plastic oil cap came loose).

    The instructions are the same as the 2006 DLR rebuild (http://www.scribd.com/doc/14893815/I...LR2-EXCELLENT), except I was able to do without removing the fork by removing the wheel, loosened the stem bolts to move the bar out of the way, and took off the brake so I would not contaminate the pads.

    The plastic cap in step 20 had come loose. I refilled with 5wt oil (I bought some from a motorcycle shop) and tighten the washer.

    No problem with any disc brake unless you plan on slapping on a 300mm rotor.

    I found this exact same issue and I'm trying to remedy it. How much oil is required in the damper? Is it 5wt shock oil? I sent you a P.M. in regards to this with further questions as I can't get your link to work.

    I sent you a PM.

    BTW, I bought some 5wt Repsol fork oil at a motorcycle store closeout. I had no idea I would actually use it someday!

    Got your PM and your e-mail. Thanks for the assistance. Worked on it tonight. Used 2.5 wt oil though as I heard that was an option as well. I hope it's ok as that's all we had. That or 7 wt. Lock out seems to be working again. Haven't been able to test ride though. We greased the o-rings of the damper with a very light Answer products grease. I know we didn't do things exactly by the book but it got me up and running for now.

    LEFTY MAX PBR Oil Leak.

    Hi,

    I've have my 2010 RZ140 since May and it's just gone back to the shop for a second time to have the LEFTY MAX looked at. I get oil leaking from the bottom of the boot and the lock-out stops working. The first time it got sent to the UK distributor who took it apart and rebuilt it with a comment on the trouble-ticket that the lock-out "still bled a little" - To me that sounded as they hadn't fixed anything and sure enough after one ride it has leaked again. I'm not doing anything extreme on it (Surrey Hills (UK) single track) and I still use my trusty F-1000sl with the ELO Lefty (had from new) which performs faultlessly (10+ years old!) so a bit disappointed by the new fork. The bike as a whole is awesome, just want the fork up to spec!

    Just wondering if this is a known issue with the MAX or have I just got a "bad" one?

    Cheers.

    Stu.

    The 140 cartridges feature a "platformesque" blow through during lockout. All the other forks over the years, haven't. Personally, I think it's a great idea, as extended riding on a locked out fork, causes the lock out shims to crack over time. with some blow through, no longer a problem.

    My guess would be that the tech who noted that, didn't realize this. Otherwise, I have no idea what they meant by the comment.

    If it's still leaking out of the cartridge, and thus, down and out of the lower end of the fork, it means one of two things. One, the cartridge is damaged in some way, and is leaking. Two, the tech that did it, didn't do it correctly, and left something out, like a seal, or didn't tighten things enough to keep them in place.

    Hi, thanks for your reply.

    Yes, the blow-through is a great feature. My old ELO Lefty is rock solid and at times I've often thought that a blow-through would be a good idea as most of my cycling buddys have "ordinary" forks with this.

    I just hope they get to the bottom of it this time. As I said before the RX140 is a pretty sweet ride I just wish the fork would keep the oil inside...

    Thanks again.

    Stu.

    Weight of lefty max 140 TPC

    I just bought one of these. I'm waiting for it to arrive, my understanding is that these are pretty heavy (over four lbs) for the alloy version.

    TIA

    Any idea of the Lefty fork offset for Flash 29?

    Looking at the 2011 Flash 29er 1. The C'dale geo is does not come up. I have been able to find just about all the specs, but the Lefty travel on that particular model (I found 90mm for the Flash 29 Carbon, so am guessing it is the same). Also no fork offset to speak of.

    Does anyone know both the fork travel and offset on that model?

    Thx.
    Grammar and spelling errors are complementary.

    Don't pull it apart....

    Wrap the axle well with duct tape, covering the sharp disc tabs well. Might even put some foam over them prior to the tape. Wrap it down tight.

    Grease the crap out of the tape, and carefully slide the boot over. It stretches nicely, so with slow steady work, it should go without issue.

    lefty rebound/sag issues????

    Wondering if anyone could be of assistance.

    I have a 2005 Prophet with Lefty Max 140mm shock. I had the Brown spring installed(replaced the red for my weight--210/215 with gear most of the time).

    Lately I have been riding trails with lots of roots and rocks...when I hit them I hear a loud metallic ping..... It sounds like the shock is rebounding really fast and making the sound. I have played with the rebound knob on top, but to no avail.

    Any thoughts on what could the the issue and/or how to fix it?
    Would shock need to be serviced or is it probably a quick fix.

    ....I don't really know how to set the sag on this spring shock....like you can do with air shocks......

    Hello,

    I need help with my 2007 Lefty MAX 140. It's off of a Prophet 5. I recently bought the bike used and there's a part on the top of the Lefty that's missing. I need help finding out what's missing, if it can be repaired and a possible estimate. Please check the photos I've posted. The bike and fork seems to ride fine. I just hate it not being 100%.

    I tried searching online for Lefty parts but can't seem to find anything. PLEASE HELP! Thank you.

    Rebound knob.

    is missing. You can find some tech info here:

    A local Cannondale shop should be able to offer some advice.

    Thank you for your response and that PDF! I tried looking for that PDF and couldn't find it, so thanks!

    Do you think that white plastic is the bottom of a broken off rebound knob? From the PDF diagram, that white plastic part doesn't have numbered part label. I'm guessing it's part of #1 on the diagram (Rebound Knob)?

    Thanks! I'm starting to feel better about the situation.

    Yes, that white plastic is the bottom of the rebound knob. The rebound shaft seats into the bottom of the plastic and the ball bearings and spring which click when rotating the rebound knob. See pg. 19, upper left-hand corner has an illustration of the knob.

    You're awesome! Thank you so much!

    You think I can find this part online so I can replace it myself? I tried searching with no luck. Will I have to contact Cannondale directly? Thanks.

    Contact your Cannondale LBS. Parts are getting scarce for the early model Lefty Max 140. I have an '05 FFD from my Prophet. I wanted to upgrade with a TPC damper, but were all sold out. Ended up buying an '07 140 with the TPC and the '05 is now just for backup and maybe parts. Check with MendonCycleSmith to see if he has what your looking for.

    UPDATE:

    I found the part! Just for future reference for others out there, the part number is #KF233. My LBS called Cannondale and said it's in stock and the MSRP is $30 USD. I ordered one and hopefully it'll be here next Friday.

    Thanks again jdinsj!

    Bottom up?

    I just bought a Flash Carbon 3, and I love it, put I can clearly feel the fork stopping in the top when it rebounds. Like bottoming out, but the other way around. I don't know what the real term is.

    Is there something wrong with the fork? Is it not adjusted properly? I tried to adjust the rebound, but it just becomes too plush.

    I have not owned an XC bike before, so don't know how these light weight fork work. I don't feel it while riding, but if I lift the front wheel or pop a wheelie, I can feel it.

    Any help is much appreciated. Thanks.
