CeramicSpeed Ceramic Race Bottom Bracket - OSBB to 24mm (Shimano) Info
A press-fit bottom bracket is only as good as its bearings — and the CeramicSpeed Ceramic Race Bottom Bracket – OSBB to 24mm (Shimano) addresses that directly. It adapts Shimano 24mm spindle cranksets to Specialized OSBB frames using ceramic bearings set in hardened-steel races, reducing rotational drag compared to standard steel bearing units. The result is a drivetrain that spins more freely and stays that way longer.
CeramicSpeed includes press-fit cups, dust covers, grease, and a decal — everything needed for a clean installation. The dust covers help shield the bearings from contamination, which matters in OSBB shells where the bearing sits close to the chainstay and sees road spray regularly.
