    Q-Factor for XTR 2011 (Trail or Race)

    Hi there,
    I am painfully sorry but I either to blind or to .... to find it, everywhere on the web it says the new 2011 XTR has a 3mm smaller Q-factor...but compared to which one???
    In particular I am interested to know the Q-factor for the XTR 2-Drivetrain Trail Version and the 3-Drivetrain, anyone have them available (SRAM XX are pretty easy to fine, even on the SRAM website...)???

    Thanks a bunch!

    The XTR Trail 26/38 cranks (same arms and BCD as Trail triple) measure 168mm Q factor.

    Hmmm, I have ordered the XTR Trail 26/38 cranks for my 2010 SC Blur XCc thinking that they would fit, but I didn't realise that they don't have a q factor of 166... (recommended by SC as the required q factor)

    Anyone clear on what the consequences of using a larger q factor crankset on a frame are??

    Is this likely to work??
