CeramicSpeed Bottom Bracket, which converts BB30 frames to fit a standard 24 mm axles like Shimano MTB.

Suitable to fit frames with a 42 mm bottom bracket shell inner diameter. The upgrade is available with standard or coated CeramicSpeed Bearings, fitted in red or black cups.

CeramicSpeed Bearings are handmade in Denmark and pressed in precision aluminium cups.

Thanks to the high-quality components, every single CeramicSpeed system is super stiff and efficient. To secure the best properties, our MTB bottom brackets come with our special Longlife grease. The BB30 Shimano MTB fitted with coated bearings delivers an increased resistance to corrosion and contaminating factors, enhancing the performance prospects of the bike and the results of the rider.

The special design of the threaded bottom bracket, where the cups are threaded and screwed together inside the frame, ensure that you avoid any creaking sounds and there is no need for any adaptors.
