    lefty fork 2013

    Hi
    this is the first time I post in the Cannondale forum .
    I have few questions for you Cannondale experts about the lefty fork.
    1) Does Cannondale offers fork only option? and if yes what s the price? ( I 'm interested in the new 2013 PBR 100 29 Hibrid.)
    2) Can lefty fork fit any frame with tapered HT or it needs to be 1.5 ?
    I m planning to build a Rocky Mountain Element 2013 as my race bike and the lefty forks look preaty nice and light .
    thanks

    thanks for the link.
    What about hubs? I have an American Classic race 29 wheelset with 15 mm qr do you know if AC sell conversion kit for lefty or what are my other options in order to use a lefty fork?

    I wanted to do the same with an Orbea or Cube....the guy at the bike store told me that it was not possible (he may have just wanted to give the easy answer). I think there should be a converter to fit 1.125

    If i m not mistaken I think I read somewhere that AC is going to offer lefty conversion kits for regolar hubs but on their site I can t find anything.
    does anybody know if I can convert a 15 mm AC hub for a lefty fork ?
    thank you

    No, you can't....disc side the axle of a lefty is way bigger than 15mm....

    How can the new Lefty be set up for 650b? Is the only difference between the PBR 29 and 26 the length of the bearing races? If so, could the 29 races be trimmed to an intermediate length to work?

    This is for a Santa Cruz TRc that I'd like to set up as 650b with a 2013 PBR.

    I dont think it can be done, you have to have a specific hub for the fork.

    Remove one internal spacer (if it's like earlier forks).

    I don't think the new forks work that way.

    from bikerumor.com

    If you’re curious as to whether you could put a 650B wheel on this, Murray says you could put it on the 29er Lefty. On the 26″ model, you’d be cutting clearance really tight and it’s not recommended. They build in 20mm of clearance for a 26×2.3 tire at the top of the tire to the bottom of the lower fork clamp. That’s under full compression and deflection, so you’d have to hit something really hard, really fast and at an aggressive angle to get the tire that close, but on a 650B wheelset with a similarly fat tire, you’d risk hitting the tire on the “crown”.

    It seems you can only order a 2013 130mm or 100mm in a 26 configuration. Will the 130mm take a 10mm travel reducer to get 120mm and better 650b clearence?

    Yes, or you could get the 29er Lefty and remove spacers as they're the same Lefty

    Not so much with the 2013 models. The length of the bearings determines the axle-to-crown measurement at bottom-out. There's no spacers to add or remove (at least as far as I can tell). I suppose you could use the typical spacers to limit the travel on a 26er model to work with a 650b wheel but you'll loose the ability to to a bearing reset since that happens at bottom-out on the new models.

    Considering dr-cannondale asked me if i wanted a 29er with reduced travel ( i told them i was gonna use a 650b wheel ) i just assumed the procedure was the same specially when they offer to change them to either 26 or 29er when buying one.
    Maybe they also change bearings ?

    Well I just got my 2013 lefty in. Configured as a 90mm 29er fork I loosened the top cap, slid the damper out and removed the 3 10mm travel spacers. I now have a 120mm 650b (20mm of room at full compression) 2013 lefty. Score!

    EDIT: still only getting 90mm travel at most....looks like its the Upper air seal that is still limiting travel...back to the drawing board....

    I have a Scalpel 26" (2012) and I want to assemble 650b/27,5" wheel in the new Lefty 2013 that I want to buy. But several people says that to use 650b in 26" frame I have to buy the Lefty 29" 90mm.

    The 29" Lefty will work fine but it will change the geometry os the Scalpel and I don't want that. The Lefty 2012 and before models can accept the 650b wheels, but the new models are very different, starting with the length (according to the Lefty owner's manual):
    - 2012 - 26" - 695mm
    - 2013 - 26" 100mm - 548mm
    - 2013 - 29" 90mm - 578mm

    Does anyone already try the new Lefty 2013 26" 100mm with 650b?
    Any photos of it and experience?

    You are one of the only people I have found with a 2013 lefty.
    I have one to and was just wondering if you have had any problems yet with water. I know they redid the whole lower leg so that water wasn't supposed to be an issue, however I was just wondering if you came across anything.

    I too am looking into a 2013 Lefty for my 650b Rush Carbon. I'd hate to lose 10mm of travel (if I go 100mm) but I am thinking 120mm on my Rush may not work with the 650b mod. Presently I use the Speed Carbon 110SL that came with the bike and it works great with the 650b wheel... clearance of a few mm's when fully compressed with a 2.3 NeoMoto tire.

    Hrm.
