All CeramicSpeed bearings are handmade in Denmark. The super smooth Grade 3 CeramicSpeed silicon nitride balls are matched (within microns) with hardened steel races that feature an ultra smooth polished groove. The balls are held in place by a reinforced polyamide cage.
Each bearing is optimized with a low viscosity CeramicSpeed "blue grease" to minimize friction and increase bearing life. The bearings are completed with non-contact seals that prevent the ingress of dirt and moisture. CeramicSpeed bearings can be used for any cycling discipline: Road, TT, Tri, Track, Cyclocross, and MTB. The benefits are super low friction, better power transfer, and extended bearing life.
During the manufacturing process, we hand-check each bearing four times to ensure all parts fit perfectly.
CeramicSpeed balls are 400% smoother, 128% harder, and 58% lighter than the standard steel bearings typically used in the bicycle industry. When comparing CeramicSpeed balls to other ceramic balls in the industry, you will find that CeramicSpeed balls are 15% harder, have 99% higher load ratings, and are 100% smoother.
