CeramicSpeed 3/16" (4.762 mm) bearing balls
In every bearing, CeramicSpeed uses 3rd grade silicon nitride balls, which have the best possible surface finish and roundness, thus ensuring not only low friction when fitted into hardened steel races, but also unparalleled bearing life. In the development of bearings for extreme performance combined with excellent durability, it is essential that the ceramic balls have an excellent surface finish quality. Thanks to their high quality, CeramicSpeed balls are 400% smoother, 128% harder, and 58% lighter than standard steel balls commonly used in bicycle components.
