CeramicSpeed 61806-2RSFT9H/HC5 Steering Bearings

The CeramicSpeed 61806-2RSFT9H/HC5 steering bearings are handmade in Denmark. The super-smooth grade 3 CeramicSpeed balls are fitted (to micron precision) with hardened steel raceways featuring an ultra-smooth polished groove. The balls are held in place by a reinforced polyamide cage. Each bearing is optimised with a low-viscosity CeramicSpeed "blue grease" to minimise 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, Cross and MTB. The benefits are super low friction, improved power transfer and longer bearing life.During the manufacturing process, we check each bearing four times by hand to ensure that all parts fit perfectly. CeramicSpeed balls are 400% softer, 128% harder and 58% lighter than standard steel bearings normally used in the bicycle industry.
