CeramicSpeed BB ALPHA for T47/86 Shimano Road

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 24 mm spindle crank from Shimano (or other manufacturers) with a T47 threaded frame (85–86 mm wide, inboard bearings).
