CeramicSpeed Ceramic Race Coated Bottom Bracket - OSBB to BB30

The CeramicSpeed Ceramic Race Coated Bottom Bracket – OSBB to BB30 solves a specific problem cleanly: running a BB30 30mm spindle crankset in a Specialized OSBB frame, without compromising the drivetrain efficiency that motivated the upgrade in the first place. The coated ceramic bearings pair ceramic balls with hardened-steel coated races — a construction designed to reduce friction and resist corrosion more effectively than standard steel bearings over time.

The coating on the races adds durability where press-fit bottom brackets are most vulnerable — moisture ingress and contaminant wear. Each kit includes two bearing cups, dust covers, grease, and decals, so installation is straightforward from the box.
