The CeramicSpeed BB ALPHA BSA SRAM DUB bottom bracket pairs hardened stainless-steel races with hand-built grade-3 silicon nitride ceramic balls for smooth, low-friction rotation. Custom seals and precision dust covers guard against moisture intrusion, helping the bearings maintain consistent performance through wet rides and varied conditions on the road, in triathlon, or on the track.
Built for BSA (English) threaded 68 mm bottom bracket shells, this bottom bracket accepts SRAM DUB cranksets with a 28.99 mm axle and a 69.0 mm crank width. A simplified spacer tube and lighter cups trim roughly 10% weight from earlier generations, and the kit includes a DUB spacer kit, UFO TECH grease, and a decal, backed by CeramicSpeed's lifetime warranty.
