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 bicycle crank 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 6806 bearings fit in all BBInfinite modules designed for use with a 30mm spindle crank set, and are just what's needed for any BB30 application using a 30mm spindle crank set. Will also work in any application where 6806 bearings are called for.
