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!
