    new crank

    Hi a friend of mine wants to change his crankset on his 2012 superfly 100 AL. I searched abouth this and its spinning my mind, I don't want to order the wrong crank, He just needs the crank not the bottom bracket so what
    crank will fit no problem on the superfly AL ??? its a 3x10 .

    shimano xt ? xtr ? sram xo x9 ?

    Base SF100AL? It's got to be Sram if he doesn't want to get a new bottom bracket also.
    Worked at Trek/Fisher dealer 2008-2013. Only a little biased.

    BB30 cranks will not work. GXP is what you need. The SF100AL frame is BB92. There are a few bb options, sometimes referred to as BB86-91. If you want to go Shimano, just make sure sure the bb says it's for Shimano.
