BB30 to 24mm MTB
Do you have a MTB frame with a 68 or 73 mm non threaded bottom bracket shell? If yes does that shell also have the internal diameter of 42 mm? Yes. Are you trying to run a 24 mm crank, like a Rotor 3D or Shimano XT? Well then you have come to the right place for a new Bottom Bracket. Choose below from your choice of Red Rotor cups with Enduro ceramic Grade 5 or ZERO bearings or Black Cups with Steel, Grade 5, or Zero Enduro bearings. If you are using a GXP Crank spindle please note that there is a specific GXP designation when ordering.
