A bottom bracket built to outlast your frame. The BB ALPHA is the result of a complete overhaul of our previous BB design, where each individual product element has been meticulously examined and optimised to create the best bottom bracket on the market. The BB ALPHA project didn’t arise from a need to fix any recurring product issues, but rather from our foundational desire to constantly improve in our pursuit of perfection.

BB ALPHA features hardened stainless-steel races hand-built with grade-3 Silicon Nitride ceramic balls, custom-engineered seals, and precision dust covers, delivering up to 500% better moisture protection, while still providing ultra-low friction performance. The simplified spacer tube design and lighter cups ensure quick installation and a 10% weight reduction over previous generations. All CeramicSpeed BB ALPHA models are backed by a lifetime warranty.

Precisely pair a SRAM DUB crankset with 28.99 mm axle with a BSA or English threaded frame by selecting this high quality bottom bracket from CeramicSpeed.
