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 group 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 its Di2 components also use wireless technology to further simplify operation and ensure smooth shifting.
