CeramicSpeed Bottom Bracket which matches BB30 frames to fit standard 24 mm axles like Shimano road cranks. Compatible with frames with a 42 mm bottom bracket shell inner diameter. Available with both standard and coated bearings, with red or black cups.
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.
