Optimize your wheel with CeramicSpeed Wheel Kits and feel the difference immediately. A CeramicSpeed Wheel Kit reduces friction – the result is a higher maximum speed. Bearing life is proven to be 3-5 times longer than standard wheel bearings. The high speed of wheel bearings means bearing friction can have a huge impact on performance. Campagnolo and Fulcrum hubs, both front and rear, use loose balls in a cotter pin and cone design. The cassette body on Campagnolo and Fulcrum uses two bearings. Note: Fulcrum R5 is not compatible with these kits. In the package: 60 CeramicSpeed 5/32” UFO TECH Balls for All Round Bearings Decal
