CeramicSpeed Bottom Brackets offer the lowest friction and best power transfer. By manually assembling each bearing, we are able to check the quality of each bearing and ensure that the fit is 100% precise. The BB30 standard, matched with the lightweight of the CeramicSpeed Bearings and our high quality components, results into a bottom bracket of unparalleled quality. Selecting the coated bearings, you will benefit from even lower friction and longer lifetime.
