CeramicSpeed 61804 Standard Bearing

All CeramicSpeed Bearings are hand-built in Denmark. Each bearing uses ultra-smooth grade 3 Silicon Nitride balls, matched to within microns with hardened steel raceways that feature a highly polished groove. The balls are retained by a reinforced polyamide cage for optimal performance.

Performance and Longevity

Every bearing is optimised with low-viscosity CeramicSpeed “Blue Grease” to minimise friction and extend bearing life. Non-contact seals keep dirt and moisture out, ensuring consistent performance across all cycling disciplines including Road, TT, Triathlon, Track, Cyclocross, and MTB. The result is lower friction, improved power transfer, and increased longevity.

Precision Matched

Each bearing is inspected by hand four times during the building process to guarantee all components are perfectly matched and assembled to the highest standard.

Material Advantages

CeramicSpeed Balls are 400% smoother, 128% harder, and 58% lighter than standard steel balls used in most bicycle bearings. Compared with other ceramic balls on the market, CeramicSpeed Balls are 15% harder, can handle 99% higher loads, and are 100% smoother.
