In developing the Ultegra R8100 series, Shimano took a holistic and 100% performance-oriented approach, because great speed comes with great responsibility. Faster than ever before, this 12-speed road bike groupset delivers unmatched control and comfort anytime, anywhere – whether in a mass-start race, chasing a personal best, or on a friendly ride with friends.
As with the Dura-Ace R9200, not only does Hyperglide+ make its way into the Ultegra components, but its Di2 components also rely on wireless technology to further simplify operation and ensure smooth shifting.
