CeramicSpeed BB Alpha DUB T47 68x29 mm Bottom Bracket for SRAM Road
The CeramicSpeed BB Alpha DUB T47 68 mm Bottom Bracket is designed to offer extreme performance, superior durability, and minimal friction, built to last longer than the frame itself. A top-quality solution made for demanding riders, competitions, and intensive use on road, triathlon, and track.
The BB Alpha uses hardened stainless steel races, hand-assembled with grade 3 Silicon Nitride ceramic balls, paired with custom seals and precision dust covers. This combination ensures up to 500% improved moisture protection, while maintaining the legendary ultra-low friction smoothness typical of CeramicSpeed.
The new design with simplified spacer tube and lightened cups allows for quick installation and a 10% weight reduction compared to previous generations. All CeramicSpeed BB Alpha bottom brackets come with a lifetime warranty, confirming their very high build quality.
