    New question here. XT M752 cranks fit '04 SJ FSR expert?

    Will these cranks fit the existing bb or do I need a new bb? if so what spindle length?

    Thanks for replies!

    but the quirk about '03 XT cranks is that there is but one BB on the planet you can use. Okay two, but they are nearly identical. The ES70 and ES71. The only difference is some anti-corrosion plating, methinks. I would think the 04 FSR is similar to the '03.

    I have an '03 stumpy, and it takes a 68x113 sized BB. I also happen to have that crankset. Works great. I have about 3-4k miles on it, I destroyed one BB (sand got past the bearing seals when crossing a stream) and it is only now starting to develop a tad of a tick to it. I think it's the spider/crank arm interface. My only real complaint is that the rings are pretty soft and prone to wear. I replace my middle ring about once a season. I switched to Vuelta rings this year, so we'll see if they are any better.

    Thanks for the info, now I am trying to decide between

    M580LX - $80
    M760XT - $180
    M960XTR - $300

    Not sure what best value is looking for stiffness & weight savings!
