Shimano Ultegra CS-R8101-12 Shimano released the new CS-R8101 cassette alongside mechanical GRX and 105. Technically, the current CS-R7100 and CS-R8100 aren't designed for mechanical shifting. However, both the 105 CS-R7101 and Ultegra CS-R8101 cassettes are compatible with both Di2 and mechanical shift systems. These cassettes use HyperGlide+ which has transformed off-road shifting with smooth, precise gear changes in both directions. Now, this technology is set to redefine road cycling. Whether pushing hard on a climb or sprinting against a friend, riders can shift seamlessly under load. Refined 12 step gear combination provides peak efficiency and accelerating performance for every racing situation. Faster, smoother shifts under maximum pedalling force. Compatible with new 12-speed and road 11-speed freehub bodies.
