CeramicSpeed 61810 (6810) Rodamiento de bolas 50x65x7mm

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.
