Alto Ceramitech Wheel Bearing Kit (6pcs, complete kit)


Size Guide

This BBInfinite Ceramitech kit replaces all the bearings in Alto Cycling road wheel hubs and freehubs. Only for rim brake wheels. Fits all non-disc, 2015 and up wheels.


1) Ceramitech bicycle wheel bearings feature Grade 5 balls, the highest quality aerospace grade available. Precise internal tolerances mean you get the smoothest rolling assemblies possible.

2) Ceramitech bicycle wheel bearings are extremely wear resistant because our ceramic material is much harder than the hardest steel bearings. Expensive bearings need to last, and last, and these do.

3) Our silicon nitride balls are 60% lighter than steel balls. Not just important to the weight weenies out there, this lower mass means faster spin up, and that’s speed, baby.

4) Our special low-contact seals and Kluber Iso Flex grease mean Ceramitech bicycle wheel bearings have 20-30 times lower friction than steel bearings with standard seals and standard lubrication. Go stir a tub of axle grease. Now stir some oil. Any questions?

Unlike many “ceramic kits” on the market, our ceramic ball bearing kit for Alto Cycling wheel hubs replace every bearing in your wheel set and not just the hub bearings. Efficiency is the new Aero. You’re already turning the wheels, so why not go faster with his ceramic ball bearing kit for Alto Cycling wheel hubs?

more about ceramitech bearings

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.
