Bearing 61802 (6802)

All CeramicSpeed bearings are handcrafted in Denmark. The super smooth Grade 3 CeramicSpeed silicon nitride balls match (within microns) hardened steel raceways that feature an ultra-smooth polished groove. The balls are held in place by a reinforced polyamide cage.

All bearings are optimized with a low-viscosity CeramicSpeed "blue grease" to minimize friction and increase bearing life. Non-contact seals complete the bearings, keeping dirt and moisture out. CeramicSpeed bearings can be used in any cycling discipline: Road, TT, Tri, Track, Cyclocross, and MTB. The benefits are super low friction, improved power transfer, and extended bearing life.

During the manufacturing process, we check each bearing four times by hand to ensure that all parts fit perfectly.

CeramicSpeed bearings are 400% smoother, 128% harder, and 58% lighter than 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 loads, and are 100% smoother.
