The Shimano Ultegra R8020 Disc groupset provides excellent braking and shifting performance thanks to new techniques adopted from the Shimano R9100 Dura Ace groupset. These new features include the Shadow rear derailleur that is better protected against external damage due to the alignment underneath the cassette, a more compact design and cable adjustment of the front derailleur, well-dosable braking force in the shifters, powerful brake calipers and a crankset with an improved power efficiency and transmission.

The Hollowtech II crankset will help you transfer more power into speed. It offers weight reduction without sacrificing stiffness. It enables a wide range of gear combinations to suit your every need. Paired with the new front and rear derailleurs, your shifts will be so fast and reliable you’ll almost question whether they happened at all! The beautifully shaped crankarm, trickled down from Dura-Ace, is a tribute to the aesthetics of your bike.
The FD-R8000 front derailleur provides for ultra-smooth shifting. It flawlessly moves your chain up and down, without extra effort. The result is a shift that is precise and direct, with no delay.
The RD-R8050 will help you maintain race concentration through intuitive shift control. The new low-profile design of Shimano Shadow RD increases its shift stability and gives the rear derailleur a sleek and integrated appearance. Race endurance is guaranteed, through the optimized slant angle. The wide compatibility of two specific rear derailleurs (GS and SS) for cassettes 11-25T to 11-30T and 11-28T to 11-34T will secure a smooth ride in even the highest and steepest mountain areas.
In addition to the benefits of the ST-R8000, the ST-R8020 adds an extra bonus in combination with the hydraulic disc brake: better rider control in all conditions. The small bracket size feels great on the palms and improves the ergonomics.
Superior choice is at the heart of our rider-tuned philosophy. With gear combinations 11-25T, 11-28T, 11-30T, 11-32T, 12-25T, 14-28T and 11-34T (CS-HG800-11) you’ll have all the options you need to tune your ride.
The BR-R8070 Hydraulic Disc Brake Caliper provides the next stage of control, allowing the rider to exert advanced brake performance in all conditions. Its sleek design integrates seamlessly in your bike’s profile.
