The Shimano Ultegra CS-R8100 cassette is characterised by seamless shifting processes that not only ensure quiet cruising, but also allow the rider to devote their full concentration to climbs and sprints. This is made possible by theHyperglide+technology which has already been able to convince in the MTB segment with smooth shifting processes in both directions across the entire gear range.

Even under maximum effort or in a direct duel with the opponent, smooth upshifting and downshifting can be realised, while larger teeth maintain maximum efficiency. And the 12-speed cassette is even compatible with Shimano’s previous 11-speed freewheel bodies.
