The medium class Primus among the switching groups in a new guise! The black and anthracite R8000 component group not only improves the appearance of your bike with its distinctive, coordinated design, but also technically makes the Ultegra a big step forward. This is partly due to the Dura Ace 9100 adopted technologies.
The Ultegra cassette is characterized by high switching performance and high wear resistance. The gear changes are extremely precise so that the switching pauses are very short. An intelligent material mix of aluminum, carbon and steel increases the life, but at the same time reduces the weight of the cassette. Thus, the largest 4 pinions are connected to an aluminum spider and the following 2 pinions with a spider of carbon. The CS-R8000 cassette is available in 6 different grades to suit every application and terrain.
