Shimano Ultegra CS-R8101 Cassette 11-34 12 Speed

The CS-R8101-12 is a 12-speed cassette from the Shimano road bike series. In contrast to the CS-R8100, it is compatible with both electronic and mechanical groupsets. It features Hyperglide+ technology, which was first tested in the MTB sector and ensures seamless shifting even under heavy load. Even when you are riding out of the saddle or sprinting, you can shift safely and immediately. The gradations have been selected to ensure high gear efficiency in all situations as well as optimal acceleration. The enlarged teeth of the pinions also contribute to this. A special plus point is its compatibility: CS-R8101 not only fits on the special 12-speed freehub body, but can also be used with conventional Shimano road freehub bodies. All sprockets are made of steel, with two lightweight aluminium sprocket carriers.
