61901 Standard Bearing

CeramicSpeed 61901 Standard Bearing

All CeramicSpeed bearings are hand-built in Denmark. Super smooth grade 3 Silicon Nitride balls are matched within microns to hardened steel raceways that feature an ultra-smooth polished groove. The balls are held securely by a reinforced polyamide cage.

Optimised Lubrication and Sealing

Each bearing is optimised with low-viscosity CeramicSpeed “Blue Grease” to reduce friction and extend bearing life. Non-contact seals keep dirt and moisture out, ensuring reliable performance.

Suitable for All Cycling Disciplines

CeramicSpeed bearings can be used across all cycling disciplines including road, time trial, triathlon, track, cyclocross, and mountain biking. Benefits include extremely low friction, improved power transfer, and increased durability.

Stringent Quality Control

During the assembly process, each bearing is checked by hand four times to ensure perfect matching and quality.

Material Advantages

CeramicSpeed balls are 400% smoother, 128% harder, and 58% lighter than standard steel balls typically used in bicycle bearings. Compared to other ceramic balls in the industry, CeramicSpeed balls are 15% harder, can withstand 99% higher loads, and are 100% smoother.
