Shimano Ultegra CS-R8100 Cassette 12-Speed 11-34T Cassette

Experience consistent and efficient shifting with the Shimano Ultegra CS-R8100 12-speed Cassette, designed for seamless performance.

The CS-R8100 is the first cassette from Shimano's Ultegra road bike series to have 12 sprockets. It features Hyperglide+ technology, which was first tested in the MTB sector and ensures seamless shifting even under heavy load. You can even change gears safely and instantly when pedalling or sprinting. 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-R8100 not only fits on the new 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.
