Shimano Ultegra R8100 Powermeter Groupset - Di2 | 2x12-speed

Ultegra R8100 – Leave Time Behind

In developing the Ultegra R8100 series, Shimano took a holistic and 100% performance-oriented approach, because size does not come without responsibility. Faster than ever before, this 12-speed road bike groupset delivers unmatched control and comfort anytime, anywhere—whether you’re racing in a mass-start event, chasing a personal best, or enjoying 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.
