CERAMICSPEED BB30 Sram GXP Coated Bottom Bracket Cup

When you want to install the SRAM or Quarq 24/22 mm diameter thru-axle crank in a 68 mm wide and 42 mm diameter bottom bracket housing, you need the BB30 SRAM GXP CeramicSpeed bottom bracket..

CS bearings are assembled by hand and installed in aluminum cups that join for silent durability without adapters.

There are two bearing options.

The first option is our standard low strength and long lasting bearing, with hardened steel tracks and our super round CeramicSpeed balls.

The second option is our Coated Bearing, which uses those same balls installed on hardened steel coated tracks for longer life and less bearing resistance.
