CeramicSpeed's BB ALPHA represents the pinnacle of bottom bracket engineering, combining hardened stainless-steel races with grade-3 Silicon Nitride ceramic balls for uncompromising durability and performance. The advanced seal system delivers 500% superior moisture protection—critical for gravel and all-weather riding—while maintaining ultra-low friction characteristics. A refined spacer tube design cuts weight by 10% and streamlines installation on T47 threaded frames. Engineered specifically for SRAM DUB cranksets with 28.99mm axles on 85-86mm wide frames, this BB ALPHA ensures precise compatibility and optimal bearing placement. Backed by a lifetime warranty, it's built to outlast your frame.
