The CeramicSpeed BB86 Road Bottom Brackets are compatible with press-fit specific bike frames only. The shell diameter is 41mm ID, and when the bearings and cups are pressed in, they fit the 24/22mm SRAM, Quarq spindle and 24mm Shimano. 

There are two versions of the CeramicSpeed Bearings that come installed in the cups. The first is our low drag, long life Standard Bearing, with hardened-steel races and our super round CeramicSpeed Balls. The Coated Bearing is our second version, which uses those same balls installed on coated, hardened-steel races for longer life and lower drag.
