I'm a newb when it comes to this type of thing so I apologize if these are elementary questions. I'm looking to change my setup over to a 1x9 from the stock X7 GXP 3X9. My question is in regards to crank compatibility with the 68mm bottom bracket. And also what bottom bracket can I use? My bike doesn't have external cups so can I use the GXP bottom bracket seen here Sram Team GXP Bottom Bracket > Components > Drivetrain > Bottom Brackets | Jenson USA Online Bike Shop even though it has external cups? Any insight and feedback is greatly appreciated.
