UCB NanoTec: 

Newest SELF LUBRICATING, SELF HEALING bearings, the fastest most reliable bearings we have ever produced.

Nano susbstrate coated races (whole bearing), giving the fastest bearings,compare to any on the market, that is our challenge! At 88 grams complete, cnc delrin cupset in black. Fully interchangeable with all 24mm axle compatible cranksets. 

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.Nano substrate treated races (which is not merely coated) but is actually a nano lubricating treatment that,fuses  the lubricant into the material substrate, and becomes a frictionless integral surface of the bearing races.

When complete, the changes the surface of the bearing races, makes the super slippery frictionless surface an integral part of the bearing material.

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 0.08 on the rolling element surface, even when dry, and with two 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 0.16 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.
