Ceramic bearings are not only here to stay, they are becoming the standard. When carbon fiber was first introduced, there was some doubt, but now every bicycle in the Tour de France is made of carbon fiber. This is the case for ceramic bearings, and the CH bearings are an excellent choice of entry into the technology. ABEC-5 tolerances and LLB seals with Graphite Nylon retainers are premium features that are not available on our competitor’s Ceramic Hybrid bearings at 2 or 3 times the cost. Oversized ceramic balls and cryogenic treatment of the ABEC-5 races ensure long lasting, smooth rolling bearings at great value.
