When you want to install a SRAM or Quarq crankset for 24/22mm diameter spindle axles into a 68mm wide bottom bracket shell with a 42mm diameter, you need the CeramicSpeed BB30 SRAM GXP bottom bracket. CeramicSpeed bearings are hand-assembled and installed in aluminum cups that screw together for silent, adapter-free durability. There are two bearing options. The first choice is our low-resistance, long-life Standard Bearing, with hardened steel races and our super-spherical CeramicSpeed balls. The second choice is our Coated Bearing, which uses the same balls mounted on hardened steel races that are coated for longer life and lower bearing resistance.
