CeramicSpeed 61803/6803 Coated bearing 17x26x5 mm

CeramicSpeed 61803 "Coated" wheel hub bearings are the most efficient on the market. Their bearing rings have an ultra-thin metal coating that is 75% harder than hardened steel. CeramicSpeed balls are 400% smoother, 128% harder and 58% lighter than standard steel bearings. This combination gives them a lifespan 7.5 times longer than conventional ceramic bearings and reduces friction by almost 75%. These bearings can be used on road, track or mountain bikes.

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.
