CeramicSpeed: the world’s leading supplier of ceramic bearings.

At the heart of every Black Inc wheel are CeramicSpeed’s premium quality ceramic bearings. 

Upgrading the rotating parts on a bike liberates additional speed that you can feel. Black Inc was one of the first companies to partner with the best ceramic bearing maker in the cycling industry and designed all of our hub shells and axle tolerances around their tight tolerances. The bearings are not only a higher quality, but they ensure many seasons of maintenance-free high performance.

Unlike other wheel brands that offer “upgrades” and switch their stock bearings for ceramic ones, CeramicSpeed bearings come standard on all of our Black Inc hubs


From the start, as the first company to introduce ceramic bearing to the cycling industry, the company has grown rapidly, now consisting of 2 specialised sales channels, focusing on cycling and industrial applications.

They have more than 15 years’ experience in bearings applications and have developed close relationships with our component suppliers over the years – each of whom is the very best in their field.

CeramicSpeed bearings are based directly on the technology developed as part of NASA’s space program in the 1990s.
Today, CeramicSpeed produces hybrid bearings, using top-grade Silicon Nitride ceramic balls, which surpass traditional steel bearings in every way.

With continuous product development ceramic ball technology has now entered everyday usage, both within industrial applications and cycling.

The results are high quality, well-documented performance, with CeramicSpeed at the forefront of the field. All their bearings are assembled by hand in Denmark.
