    2011 xlr 29" & 26"

    Are the internals the same in 26 and the 29 XLR?

    The 29er XLR uses three spacers on the standard Ultra120 to get its 90mm of travel.

    Thats the Compression Piston, it goes inside the shaft and you preload the spring whit the Air Piston.

    This piston works when the oil expands whit temperature.

    The XLR dampers have different part numbers for the 29er vs 26er, Craig will know if they're really just the same though. The Solo Air upper seal and volume reducers appear to be different lengths as well. The main difference is the (external) outer lower assembly for the 29er is from the 120 and the 26er is the 100. This info is from the blown up diagrams in the Lefty manual, Craig's knowledge will usually trump that though

    BTW Craig, Drew got me fixed up....PM me if you want, it's interesting....

    Same dampers. Different #'s are just to allow them to stock them all set up for one wheel or the other.

    XLR dampers have different hardware internally for the XLR unit, but either damper can be made to work for either control unit with the addition or removal of said hardware.....

    I'll bite. PM me, what'd he do for ya?

    Whoa, back that horse up...

    It all depends what forks you are talking about. There are XLR's that use the 140mm damper and there are XLR's that use the 100mm damper. Need a few more specifics about the forks you are questioning.

    XLR 140, XLR 120, XLR 90 (29er) all use the same damper.
    XLR100 is different...and it can be 29er'd

    Very true, I was simply speaking to the difference between XLR and PBR dampers. There are indeed different dampers in those two forks.

    Thanks for clarifying!

    Basically I was just thinking about adding a 29er to the mix. Wondering if I could still use my older lefty on a new 29er. I went to the geometry sheets on the older 29 frames when all forks were 110 with a spacer vs. the geometry of the current 29 frames. As I see it the steepened up the head tube angle to make up for the fact the the new 29 lefty has a longer upper. Therefore, if I got a new frame and put a 2010 lefty on it, it would jack up the feel of the bike do to the head tube angle changing. The question I started out with was meant to say are the xlr90 and xlr100 internals the same. I know the the xlr90 fork has a longer upper than the xlr100, but I just want know if the internals are the same.
