    Crank questions.

    On a shimano xtr m970 crankset, can you put rings from the xt m770 on it?

    And none-xtr question;
    If I buy a 2012 XT crank, which is 3x10, can i put 9 speed rings on it? (From the m770)

    Thanks.

    The 3 ring cranks all have the same configuration, only the 2x10 XT cranks have deleted the outer big ring mount.

    I believe that there is s slight difference on the small ring for the M970 cranks

    The XTR 970 uses a thicker granny ring than the XT, so you would have to use spacers to use XT granny ring on the XTR cranks. The XTR granny ring is cheap enough to go with it.

    Trying to wrap my head around this. I bought a Yeti SB66 Race Build which came with the Shimano XT group. The crank it came with is the 3X10 XT FC M780 44-32-22. I want to switch to a 2X10 set up. Can I just change the chain rings or do need to switch cranks to the XT FC M785 26-38? I know I will also need to switch the front derailleur to a 2X10 model. Has anybody gone through this?
