  1. Crank/bb setups with wide Q factors irritate the knee problem that I have. Has anyone measured the
    Q factor of the new XTR? It seems like the outboard bearings for the BB would put the crankarms
    pretty far out. Do 2003 XTR crankarms sit wider than old XTR? If anyone has a set, I'd love to
    hear feedback.

    I don't know about the old ones but my new 2003 XTR BB measures at 135 mm. I stuck a long pin
    straight through the BB and measured the part that was in the tunnel 😉
