CeramicSpeed Bottom Bracket specially designed to accommodate Specialized OSBB frames. Fits frames that feature shells of 46mm inner diameter where the cups are pressed into 62mm wide frame. Suits 30mm spindled cranks like BB30/Specialized OSBB.
The CeramicSpeed Bottom Brackets are assembled by hand in Denmark and installed in aluminium cups. In addition to serious watt savings, this bottom bracket delivers longer bearing lifetime, a lightweight product, and an overall stronger and stiffer crank setup. Thanks to the non-contact seals used and the low-viscosity grease, this bottom bracket will not only improve the feel, but also your performance.
