¤
Discover the high-end performance delivered by BlackBearing B5 ceramic ball wheel hub bearings 6805-2RS. Lighter in weight, they allow you to optimise your wheels while providing better handling at very high speeds, a longer service life (several times that of a standard bearing), less friction, greater rigidity, more precision, and better mechanical characteristics.
¤To ensure that these bearings are compatible with your wheels, remove the bearings installed in your hubs and measure the various dimensions with a calliper.
