CeramicSpeed BB30 SRAM GXP MTB Bottom Bracket (Coated)

BB30 mountain bike bottom bracket shells are wider than road, 73mm, and share the same diameter; 42mm. The bottom bracket here allows you to install your SRAM or Quarq MTB crankset into a BB30 mountain bike.

This is how you get minimum drag, no adapters necessary. Our bearings are installed into aluminum cups that thread together for quiet durability. The cups come with CeramicSpeed Bearings installed, coated bearings and hardened-steel races for longer life and less bearing drag.
