Product Details

Shimano has designed the Ultegra R8100 for speed and performance, but at the same time also had the timeless nature and community experience on the road bike in mind when developing it. User-friendliness, efficiency and safety also played a major role in development.

That's why the groupset works without cables at the crucial point, namely the interaction between STIs and rear derailleur. Cables are only used between the battery and the rear derailleur or front derailleur. The wireless protocol is extremely fast and reliable, which raises the shifting speed to a new level - with consistently high precision.

A twelfth sprocket on the cassette in combination with a very clever gradation means that you have a wider gear selection at your disposal, and are optimally prepared for any terrain. In addition, Hyperglide+ technology familiar in MTB sport ensures smooth gliding of the chain even under loads. Conveniently, the Ultegra 12-speed cassettes are also compatible with older Shimano road freehubs.

Last but not least, the disc brakes have been thoroughly revised and equipped with servo-wave technology. This way, the full braking power is not only available more quickly, but can also be modulated better. A simplified bleeding process and more free space for the brake pads are further advantages.
