BB30 bearings for cranks with 30 mm axle and frames with 42 mm shell diameter. Also perfect for PF30 cups where you can replace the original bearings.
These bearings are used in all Specialized S-Works road frames.
CeramicSpeed BB bearings are used by pro teams like Omega-Pharma - QuickStep, Astana and Team Saxo-Tinkoff and professional MTB team Superior-Brentjens.
Every single bearing is hand built in Denmark under clean room conditions. All parts are selected by hand for perfect fit, each bearing is spined by hand multiple times during the building process to ensure that all parts are matched perfectly.
CeramicSpeed balls are smoother, harder and lighter than the standard steel balls which are typically used in bicycle components.
