Product Description Shimano Ultegra CS-R8101 Cassette
Shimano 105 has always offered great value for money, and this Shimano Ultegra CS-R8101 12-speed cassette is no different. The Ultegra groups shift smoothly thanks to Shimano's Hyperglide technology. This technology comes from mountain biking and ensures that shifting is smoother than ever. Small bites from the teeth of the cassette and ground off parts ensure a smooth transition. Even when shifting under pressure, for example on a climb or during a sprint between plates, shifting is smooth. You don't have to buy new wheels if you previously rode with 11-speed, the 12-speed cassette also fits older 8-11 speed Shimano/SRAM wheels.
