This CeramicSpeed 61810 (6810) (50x65x7mm) bearing for the bottom bracket provides incredible fluidity and maximum durability.
All CeramicSpeed bearings are handmade in Denmark. Super-smooth CeramicSpeed grade 3 silicon nitride balls are matched (in the micron range) to hardened steel raceways that have 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 extend bearing life. Non-contact seals complement the bearings and keep dirt and moisture out. CeramicSpeed bearings can be used for all cycling disciplines: Road, TT, Tri, Track, Cross and MTB. The advantages are extremely low friction, better power transmission and longer bearing life.
