Shimano Cassette Ultegra CS-R8100-12 (11-30) 12-Speed

Ultegra R8100 - Leave Time Behind

When developing the Ultegra R8100 series, Shimano took a holistic and 100% performance-oriented approach, because great speed means great responsibility. Faster than ever before, the 12-speed road bike groupset always and everywhere scores with incomparable control and comfort - whether in an amateur race, on the hunt for a personal best time or on a companionable ride.

As with the Dura Ace R9200, Hyperglide+ is not only used in the Ultegra components, its Di2 components also rely on wireless technology to further simplify operation and ensure smooth shifting.

The Shimano Ultegra CS-R8100 cassette is characterized by seamless shifting operations 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 Hyperglide+ technology, which has already proven itself in the MTB segment with smooth shifting in both directions across the entire gear range.

Smooth upshifts and downshifts can be achieved even under maximum effort or in a direct duel with an opponent, while larger teeth maintain maximum efficiency. And the 12-speed cassette is even compatible with Shimano's previous 11-speed freehub bodies.
