CeramicSpeed Ceramic Race Coated Bottom Bracket - PF30 to 25mm (Campy UltraTorque)

The CeramicSpeed Ceramic Race Coated Bottom Bracket PF30 to 25mm is built for Campagnolo UltraTorque cranks running in a PF30 shell — a specific fitment that rewards the attention to detail CeramicSpeed brings to every bearing system. The cups are machined aluminum, pressed into the 46mm PF30 shell, and the bearings themselves use Grade 3 Silicon Nitride ceramic balls seated in coated steel races designed to reduce friction and resist wear over long-term use.

The Race Coated designation refers to the hardened coating applied to the bearing races — a step up from standard steel that extends service intervals and keeps rolling resistance low across more kilometers. On UltraTorque cranks, the bearings press directly onto the spindle, so fitting and removal require the appropriate tools, but the long-term payoff is a drivetrain that spins with noticeably less resistance than a conventional steel bearing setup. Available in Black or Red to match your build.
