Maximum efficiency for your Cervélo. The CeramicSpeed BBright DUB bottom bracket.
This high-end bottom bracket from CeramicSpeed transforms every pedal stroke into measurable forward momentum, extracting maximum performance from your SRAM DUB crankset on a BBright frame. Precision-machined bearing cups, ultra-fast ceramic balls, and a robust seal ensure you stay faster for longer, allowing you to focus on pure performance rather than bottom bracket resistance.
Noticeably smoother running with every pedal stroke
The BBright DUB bottom bracket combines the Cervélo-specific BBright standard with the 28.99 mm SRAM DUB axle, ensuring a play-free, stiff, and extremely smooth-running connection between the frame and crank. The ultra-smooth ceramic balls from CeramicSpeed significantly reduce friction compared to standard bearings. This results in a more direct power transfer, allows you to maintain a high level of performance for longer, and provides valuable watt savings over long distances.
Built for demanding racing cyclists
High-quality bearing cups for PressFit 46 x 79 mm bottom bracket shells offer a precise, creak-free fit in your BBright frame. The special seal protects the bearing from dirt and moisture. At the same time, rolling resistance remains extremely low. This makes this bottom bracket ideal for ambitious road cyclists, time trialists, and triathletes who want every second and every watt to count.
Greater durability. Less maintenance.
CeramicSpeed ceramic bearings are designed for maximum lifespan and, when properly installed and occasionally maintained, require significantly less maintenance than conventional bearings. The successful combination of hardened raceways, precision ceramic balls, and perfectly fitting seals ensures consistently smooth operation. You'll spend more time on the road and less time in the workshop.
