CeramicSpeed BB ALPHA BBright Shimano road bottom bracket

The CeramicSpeed BB Alpha BBright Shimano is a top-of-the-range 46mm pressfit bottom bracket designed to combine a Shimano bottom bracket (24mm axle) with a standard BBright frame (79mm). Hand-assembled in Denmark, it comes with silicon nitride ceramic bearings and a lifetime warranty.

The CeramicSpeed BB Alpha BBright Shimano bottom bracket is designed for cyclists looking for the best performance from their drivetrain. Designed for frames using the BBright standard - an asymmetrical 46mm pressfit 79mm wide, mainly used by Cervélo - it allows the installation of a Shimano crankset with a 24mm axle (Dura-Ace, Ultegra, 105 or any other crankset compatible with 24mm).

The BB Alpha range from CeramicSpeed is based on hardened stainless steel races, hand-assembled with grade 3 silicon nitride balls (CeramicSpeed Balls). The bespoke seals and dust caps, optimised over 28 development iterations, offer 500% better protection against moisture and contaminants than previous generations, while maintaining ultra-low friction. The simplified spacer tube design and lightened cups allow for quick installation and a 10% reduction in weight compared to previous models CeramicSpeed.

The CeramicSpeed BB Alpha BBright Shimano is supplied with a syringe of UFO TECH All Round Bearing Grease (5 ml) and a sticker CeramicSpeed. All BB Alpha cases are covered by the CeramicSpeed lifetime warranty.
