ABEC 5 radial Ceramic Hybrid bearing with 12 mm inner diameter, 28 mm outer diameter, 8 mm thickness and double-lip type sealing with light contact, making a labyrinth seal.
Ceramic bearings are not only here to stay, they are now the standard, period. When carbon fiber was first introduced, there were many riders still on steel bikes in the Tour de France, but now every racing bike is made of carbon fiber. This is the case for ceramic bearings, and the CH bearings are an excellent choice for entry into the technology. ABEC-5 tolerances and LLB seals with Graphite Nylon retainers are premium features that are not available on Enduro Bearings competitor's ceramic hybrid bearings at two or even five times the cost. Oversized Silicon Nitride Grade 5 balls and cryogenic treatment of the ABEC-5 races ensure long lasting, smooth rolling bearings at great value.
