    I have 2011 Stumpjumper FSR Comp Carbon frame

    Bottom bracket like that:

    Truvativ Press-Fit GXP Bottom Bracket 84.5

    and I bought SRAM TRUVATIV X.0 BB30 crank set for my frame:


    Please advise me can it fit my frame or not? If not please give me some examples that I can find and buy online (Sram X9, X0, XX). Many thanks for your soon reply cause I have to complete payment within 2 days!

    I heard 166. 156 may work, but it will be super close.

    For the Hardtail SJ you can use the 156, but the FSR model needs the 168.

    I think I'm going with the 168 just for room.

    Neil, have you gotten a BG fit? You're fitter can help you with Q-factor, etc.

    I have not. I should however there is no bike fitter in crested butte, at least a professional one. I wish I could tell what I currently have and I would get what is the closest. But there is no stamp and I looked on the comp carbon specs and it does not share Q factor.

    My wife works for a Specialized store & they said definitely a 168 for the Stumpy, as well as my new Enduro 29, which I just installed 168Q XX1 cranks & they have about 3/8" clearance on each side.
