The design of overlapping cups extending through the shell for EVO386 reduce the likelihood of creaking and increase the reliability of the system.
The CeramicSpeed Standard Bearings feature an average drag reduction of 75% compared to stock bottom brackets. That translates into frictional drag of 0.3-0.4 watts per set, which is the result of great design, hardened-steel races, and ceramic balls that are 100% smoother and 15% harder than the ceramic competition.
The CeramicSpeed Coated Bearings are a step up as they reduce drag by 50% compared to our Standard Bearings and an improvement in bearing life by 60%.
All Round Grease comes standard in the bearings, but can be replaced for lower drag TT and Track Grease, or higher durability LongLife Grease, which adds a bit of drag but stays in when riding through messy conditions.
We recommend that you follow our instructions on how to maintain your CeramicSpeed Bottom Brackets to achieve the lowest friction and the best longevity
