CeramicSpeed R4 bearing, 16 x 6 x 5 mm
All CeramicSpeed bearings are handmade in Denmark. Super smooth Grade 3 Silicon Nitride CeramicSpeed balls are matched (in microns) with hardened steel races that have an ultra-smooth polished raceway. The balls are held in place by a reinforced polyamide cage. Each bearing is optimized with low-viscosity CeramicSpeed "Blue Grease" to minimize friction and extend bearing life. Bearings come with non-contact seals that keep contaminants and moisture out. CeramicSpeed bearings can be used for any cycling discipline: Road, TT, Tri, Track, Cross and MTB. Benefits include super low friction, better power transfer and increased bearing life. During the build process, we hand inspect every bearing four times to ensure all parts are perfectly matched. CeramicSpeed balls are 400% smoother, 128% harder and 58% lighter than standard steel bearings commonly used in the cycling industry. When comparing CeramicSpeed balls to other ceramic balls in the industry, you will find CeramicSpeed balls are 15% harder, withstand 99% higher loads and are 100% smoother.
