CeramicSpeed BB ALPHA for BSA SRAM DUB MTB

A bottom bracket that lasts longer than your frame. BB ALPHA relies on hardened stainless steel races, handcrafted with Grade-3 silicon nitride ceramic balls, custom-designed seals, and precision dust caps. The result: up to 500% better moisture protection while still maintaining ultra-low friction. The simplified spacer tube design and lighter cups ensure quick installation and 10% less weight compared to previous generations. All CeramicSpeed BB ALPHA models come with a lifetime warranty.

For the precise combination of a SRAM DUB crank (28.99 mm spindle) with a BSA or English-threaded frame – specifically designed for MTB use with long-life grease for higher loads and dirt.
