The CYCLINCERAMIC jockey wheels are built with highest quality 7075 aluminium. They last 4-5 times longer than standard options and dramatically reduce friction while offering smoother and more precise shifting than traditional pulley wheels. Because the rotation of the jockey wheels is 4-5 times faster than other bearings on the bike, the gains in this particular area are considerable. Our unique bearing treatment reduces friction up to 98%.
