Shimano Ultegra CS-R8100 12s cassette | 11-30

Ultegra R8100 – Leave Time Behind
When developing the Ultegra R8100 series, Shimano pursued a holistic and 100% performance-oriented approach, because high speed means great responsibility. Faster than ever before, the 12-speed Road Bike scores points everywhere with unparalleled control and comfort – whether in a public race, chasing a personal best time, or on a friendly ride with friends.

As with the Dura Ace R9200, not only does Hyperglide+ feature in the Ultegra components, but their Di2 components also use wireless technology to further simplify operation and ensure smooth shifting.

Shimano Ultegra CS-R8100-12 Cassette
The Shimano Ultegra CS-R8100 cassette is characterized by seamless shifting, which not only ensures quiet cruising, but also allows the rider to focus fully on 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.

Even when exerting maximum force or in direct competition with your opponent, you can shift up and down smoothly, while larger teeth maintain maximum efficiency. And the 12-speed cassette is even compatible with Shimano's previous 11-speed freehub bodies.
