    Vertex 950 bottom bracket upgrade question

    Hi there!

    I'm the proud owner of a new Vertex 950 and I'd like to upgrade the drivetrain. My options are Shimano's XT or SRAM's XO but I have no idea of which bottom bracket I should order or if I can still use the one that came with the bike until it breaks.

    As I live in Venezuela I need to get the order right as it is pretty much impossible to return an item from an online vendor in the US.

    I'll appreciate your help! Cheers!

    If you choose the X0 cranks, just keep the original SRAM GXP BB for the SRAM cranks that were original equipment on the bike.

    If you go with XT cranks you will need a Shimano BB-92 press fit BB. (BTW, not the BB-92-42 which is a new option, that's the wrong diameter)
