Ceramicspeed Alpha BB30/68 30 mm Road Lagersatz

A bottom bracket that lasts longer than your frame. The BB ALPHA features hardened stainless steel bearing cups that are hand-assembled with grade 3 silicon nitride ceramic balls. Specially designed seals and precise dust covers provide up to 500% better protection against moisture while maintaining extremely low friction. The simplified spacer tube design and lighter bearing cups allow for quick installation and a 10% weight reduction compared to previous generations. All CeramicSpeed BB ALPHA models come with a lifetime warranty. This high-quality bearing kit from CeramicSpeed enables the precise combination of a crank with a 30mm axle of sufficient length with a press-fit shell featuring a 42mm bearing seat and 68mm width, where the bearings are pressed directly into the frame – commonly known as BB30. Included in the package: * BB ALPHA Bearing Kit for BB30 Road * UFO All Round Grease, 5 ml * Stickers.
