BB30 bottom bracket for BB30 cranks with 30 mm axle and frames with 42 mm shell diameter. Fit standard PF30, Cervélo BBright press-fit (excepting Cervélo P5 Six) and 386EVO frames.
CeramicSpeed BB bearings are used by pro teams like Omega-Pharma - QuickStep, Astana and Team Saxo-Tinkoff and professional MTB team Superior-Brentjens.
High quality spacer included.
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.
In CeramicSpeed coated wheel kits the steel races are coated with an extremely thin (2-3 microns) protective layer, which is 75% harder than hardened steel. This is applied to the entire raceway, and makes the bearing even more resistant to contamination, as well as further reducing friction.
CeramicSpeed offers 4 years warranty for standard and 6 years for coated products - please register within 30 days after purchase at ceramicspeed.com
