These CeramicSpeed 61806 bearings deliver top-of-the-range performance. Designed to improve the efficiency of your wheels, they reduce friction and ensure better power transfer with excellent durability. CeramicSpeed balls are 400% smoother, 128% harder and 58% lighter than standard steel bearings. These bearings can be used on the road, track or mountain bike.
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.
