Ceramic Bicycle Bearings

Ceramic bicycle bearings are the heart of the bicycle. Without them, no frame or transmission advance is worth much. Over the past 20 years, however, the near universal adoption of ceramic bike bearings persuaded most mechanics to stop tinkering. Numerous bearing tricks of the past disappeared, replaced with a single chant; ˇ°make them last forever.ˇ± Issues like seal friction, grease viscosity, and tuning for speed have ped out of sight.

Our Ultra Seal line of ceramic bearings for bicycles are specially designed for On Road and relatively clean riding environments. These ceramic bicycle wheel bearings are maintenance free and lubed for life. The non-contact seal eliminates any drag typically associated with a rubber sealed bearings and still provides extra protection against external elements. All ceramic bearings for bicycle are packed in grease and will require short break in period to loosen up.
