CeramicSpeed Bottom Brackets guarantee you optimised power transfer, the lowest friction and longest product lifetime, helping you to save watts and ride faster. Fitting almost all standards available on the market, a wide range of CeramicSpeed Bottom Brackets is available for upgrading your bike. Put more of your energy into forward motion by reducing frictional drag wherever you can. CeramicSpeed Standard Bearings typically have frictional drag of 0.3 - 0.4 watts per set. That’s in the range of a 75% drag reduction compared to standard bottom brackets. CeramicSpeed balls are 100% smoother and 15% harder than our ceramic competition. Our bearings last at least three times longer than other bearings. Race Day Grease, All Round, and Long Life are greases CeramicSpeed designed to maximise smoothness. The first offers the least drag, the latter is the most durable. All Round comes as standard in road bearings, Long Life in MTB. You can change the grease to further tune performance.
