ocs NanoTec:

Superb NanoTec hybrid ceramic performance bearings,substrate nano treated hardened races, grade 5 ceramic balls, Non contact seals and nylon retainers.

We looked closely at what the rider wants from a performance product, we worked closely with some top flight athletes both on the road and track to test our products, to ensure they surpass even our exacting standards.

After numerous rigourous hours of testing in enviroments that even the die hard rider would find  difficult to re produce, we have finally made the bearings that are future proof.

NanoTec the pinnacle bearing in the world of cycling, all our know how and experience, athletes' feedback, and enviroment test results, bring the bearing that is the Ultimate in performnace, relaibilty, and economically priced.

Coeffient  of 0.18 on the rolling element surface, even when dry, and with two or three drops of some of our magical lube, give it another asistance of 0.02. Compare this with a good greased bearing with non contact seal witha friction coeffiency of 0.26 or more. and you see why we have few comparions.

We still use our ceramic knowledge to produce the roundest spheres, and we give the bearing races a substrate treatment that is guaranteed...meaning, it can run in water, without fear of corrosion, it will run dry, for maximum performance, and is self lubricating and self healing. Our bearing surfaces will keep the bearing running longer.

We have it now, no one else refines performance bearings the way we do.

We are proud to say that our bearings are being used at the London Olympic games by riders on the road, in the TT and in numerous invents in the velodrome. Chosen specifically for their performance gains, in events that are a once in a lifetime opportunity for acheivement.

Good luck all.
