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

The CeramicSpeed Ceramic Race Coated Bottom Bracket BBright to 25mm exists for a specific purpose: fitting Campagnolo UltraTorque cranks into BBright press-fit frames without compromising on bearing performance. The 25mm spindle diameter is unique to Campagnolo and Fulcrum UltraTorque systems, and this bracket is built specifically around that interface — aluminum cups machined by Rotor in Spain, pressed with CeramicSpeed's Grade 3 Silicon Nitride ceramic balls at their facility in Denmark.

Those ceramic balls are the core of what CeramicSpeed does. According to manufacturer testing, they run 400% smoother and 128% harder than standard steel balls, and carry a coated race treatment designed to further reduce friction and extend service life — with CeramicSpeed citing three to five times longer bearing life than conventional alternatives. The BBright shell standard itself — asymmetric at 79mm wide versus BB30's 68mm, with the extra width on the non-drive side — gives frame builders room to run a wider left chainstay for improved lateral stiffness. This bracket is for BBright press-fit specifically, which shares more design logic with PF30 than with BB30.
