CeramicSpeed Ceramic Race Bottom Bracket - Bbright to 30mm (Campy OverTorque)

Running Campagnolo Over-Torque cranks in a BBright Press Fit frame requires a bottom bracket that bridges two standards without compromise — the CeramicSpeed Ceramic Race Bottom Bracket BBright to 30mm (Campy OverTorque) does exactly that. The BBright shell's asymmetric 79mm-wide, 46mm inner diameter housing pairs with Over-Torque's 30mm spindle, and CeramicSpeed's aluminium cups — machined by Rotor in Spain and pressed at CeramicSpeed's facility in Denmark — handle the translation cleanly.

Inside those cups are Grade 3 Silicon Nitride ceramic balls, the same specification CeramicSpeed uses across its bearing range. Compared to standard steel balls, they are 400% smoother, 128% harder, and 58% lighter — figures that translate directly into lower rolling resistance and bearing life three to five times longer than conventional bottom brackets. The balls are fitted into hardened steel races in dust-free clean rooms, then inspected again before final assembly.
