Ceramitech 6805 bearing for all Shimano/Sram modules (pair)

Size Guide

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 bearing races are processed with additional melting and heat treatment steps. The result is a type of corrosion-resistant steel with a very uniform fine grain material structure that is then micro polished for an ultra smooth race channel. This process produces a bearing race set that is hard enough to resist ceramic-induced wear, and so smooth that there's no good place for wear to begin. Like you we measure success by comparing distance over time. With BBInfinite and Ceramitech, you'll go the distance time, and time again, faster, and faster still.

These Si3N4 hybrid 6805 bearings fit in all DirectFit Shimano and Sram GXP BBInfinite modules, as well as many other applications.
