    Which bottom brackets fit XTR M950 cranks?

    Other than the XTR M950 bottom bracket, which others will fit the M950 cranks?
    Is there an external bearing bottom bracket that will work?

    Your pretty much stuck buying an XTR V1 splined BB. The XT and lower BB's wont work because they used the V2 spline.

    Also known as Octalink v1- BB-M950 or BB-M952 are my preference. Note: be very careful when installing crank arms on the BB to make sure the splines line up properly before tightening otherwise you can munch either or both the crank arm or BB splines. I move the crank arms back and forth a bit when installing to make sure they are on all the way before tightening.

    You can also use Shimano Road Octalink BB's depending on what chainline your after.
