With Trek BB90, the bearings press directly into the frame. The Trek BB90 GXP bearings work with all GXP road bike crank systems from Sram and other manufacturers.

Ceramitech Bearings: The Si3n4 hybrid ceramic bearings feature ultra-spherical silicon nitride balls matched to SAE 52100 chrome steel bearing races that have been processed with additional heat treatment and polishing steps. The result is a hybrid-ceramic bearing that lasts longer than any steel bearing with spin performance no steel bearing can rival. These bearings feature mid-contact seals for extreme performance and endurance.
