Parasitic drag is the enemy within any machine. Frictional losses pile on bit by bit, consuming effort that should be moving you forward. But in any ceramic bearing it's not the balls that wear out, it's the races, which soon fail, causing wattage-sapping drag. That's why our Ceramitech Shimano and Sram GXP bearings are processed with additional melting and heat treatment steps.
These Si3N4 hybrid 6805 bearings fit in all DirectFit Shimano and Sram GXP BBInfinite modules, as well as many other applications.
