Using precision machined 7075 aluminum and a patented design, the KCNC rear derailleur jockey pulleys feature sealed ceramic bearings and come a variety of colors including black, red, blue, silver and green. Ceramic bearings have been shown to reduce friction over conventional bearings and have the added benefits of lighter weight and greater durability. KCNC uses ceramic bearings to give greater longevity and reduce weight over standard bearings. A pair of KCNC jockey pulleys weigh 18-grams and are available in 10, 11, 12 or 13 tooth versions. The KCNC jockey pulleys fit Shimano DuraAce, Ultegra and 105, as well as SRAM Red, Force and Rival derailleurs.
