    Help needed with upgrade



    I just bought a new bike (Motobecane Ti MTB) that comes with a FSA Comet MegaExo 3x10 and a FSA BB-7000 / 73mm MEGAEXO BB.

    I need to change it to a 170mm setup. I saw a Sram X0 I liked on sale: Sram X.0 BB30 Triple Crankset.

    Considering what my bike has now, which Sram BB do I need?

    Thanks in advance.

    I don't think you can use that BB30 crankset in a bottom bracket designed for a threaded shell. The FSA megaexo and SRAM GXP cranksets use a 24mm spindle, and there just enough enough room in the bottom bracket shell for a 30mm spindle of the BB30.

    Going to have to stick with a crankset that uses a threaded bottom bracket.

    Would this one work? Sram X.0 GXP Triple Crankset - 10 Speed

    Using this BB? SRAM GXP Team Bottom Bracket English threading

    Thanks!

    Yeah, the GXP bottom bracket is the one you want.
