CO 6806 LLB - ABEC-5, Enduro Zero, Ceramic-Hybrid Black Oxide treated radial bearing - 30mm x 42mm x 7mm -
Enduro Zero Ceramic-Hybrid Radial bottom bracket Bearing featuring Black-Oxide treated 52100 High-Carbon chromium alloy races paired with grade 5 Silicon-Nitride Ceramic balls with 90% fill, high-pressure, water-proof grease. Si3N4 ceramic balls reduce bearing wear and increase bearing life by eliminating steel on steel contact within the bearing. Black oxide/magnetite treatment to the races provides an extra level of corrosion resistance and extended worry-free performance.
The most common use for this bearing is as a direct replacement bearing for BB30, PF30 and BB386 and most other bottom brackets with a 30mm OD spindle.
