The CeramicSpeed Standard Bearings last at least three times longer than other bearings. Thanks goes to hardened-steel races and CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. These have a frictional drag of 0.3-0.4 watts per set, which represents an average 75% drag reduction compared to most bb’s.
The CeramicSpeed Coated Bearings reduce drag by 50% compared to CeramicSpeed Standard Bearings and an improvement in bearing life of 60%.
The grease that comes installed can be changed. All Round Grease is standard, 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.
In The Box
1 bottom bracket with bearings installed.
2 dust covers.
10ml syringe of All Round Grease.
Super smooth, super round CeramicSpeed Balls contained in hardened-steel races are found on both versions. The Coated version has a metallic coating laid onto the races, making it even smoother and harder, resulting in lower drag and longer life.
