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 Race Day Grease, or higher durability Long Life Grease, which adds a bit of drag but stays in when riding through messy conditions.
