    XT M770 Crank: can interchange 9spd & 10sd crank arms?

    hi guys, here's the scenario...

    im using 9speed 22-32-44 170mm, i need 175mm... my friend has 10speed 24-32-42 175mm, he needs 170mm. can we swap crank arm with no issues?

    I imagine so. Chainrings aren't crank length specific.
