The CeramicSpeed BB86 SRAM GXP road bike bottom brackets are exclusively compatible with specific press-fit frames. The bottom bracket shell diameter is 41 mm ID and, once the bearings and cups are pressed, they fit the 24/22 mm SRAM and Quarq spindle. There are two versions of the CeramicSpeed bearings mounted in the cups. The first is our low-resistance, long-life Standard Bearing, with hardened steel races and our super-round CeramicSpeed balls. The Coated Bearing is our second version, which uses the same balls mounted on hardened steel races that are coated for even longer life and lower resistance.
