CeramicSpeed BB ALPHA BBright (SRAM DUB Road)

The CeramicSpeed BB ALPHA for BBright SRAM DUB Road is specifically designed for BBright pressfit frames featuring a 46mm asymmetric shell with a width of 79mm, perfectly matched to SRAM DUB road cranksets with a 28.99mm axle.

BB ALPHA represents the next generation of CeramicSpeed bottom brackets. At its core are hardened stainless-steel bearing races, hand-assembled in Denmark with Grade 3 Silicon Nitride ceramic balls, delivering CeramicSpeed’s signature ultra-low friction while dramatically increasing corrosion resistance and long-term durability.

A newly developed low-contact seal system combined with high-stiffness POM dust covers improves protection against moisture and contamination by up to 500%, without compromising drivetrain efficiency. The bottom bracket cups are CNC-machined from 7075 aluminum alloy, allowing a lighter, stronger construction and achieving an overall 10% weight reduction compared to previous generations.

Backed by over 1,000,000 km of laboratory and real-world testing and covered by a lifetime warranty, BB ALPHA is built to be the last bottom bracket you will ever need.
