Eagerly anticipated, the updated Shimano Ultegra R8000 11-Speed Groupset has arrived. It was never going to be easy to improve on the Ultegra 6800 but there are clear improvements on aesthetics and performance. Shimano has evolved the Ultegra series, which hugely benefits from the joys of its bigger brother's technology, Dura Ace R9000. Infused with state-of-the-art technology, the Shimano Ultegra R8000 11-Speed Groupset is superbly stiff, light, and responsive. This Ultegra groupset is a major upgrade on any racing or training Road Bike.

FC-R8000 Hollowtech II Crankset

This FC-R8000 Hollowtech II Crankset will make sure you transfer power into speed. With the added bonus of offering weight reduction without sacrificing stiffness, this crankset supports a wide range of gear combinations to suit the fastest downhill section and the steepest mountain pass. The crankarm is redesigned to provide your bike with a fine aesthetic upgrade.

Ultegra Brake Set BR-R8000
Enhanced with a new, sleek design, the Ultegra caliper brake has narrower gaps between the arms for a reduced profile and compatibility with 28c tyres. The stabiliser between the axles improves the braking performance by delivering clear contact to bring you to a balanced stop.
11-Speed R8000 Ultegra Cassette
At the heart of Shimano's 'rider-tuned philosophy' lies their belief in offering superior choice. With a huge range of cassette options, you'll conquer any terrain.
Ultegra 11-speed Chain CN-HG701-11 114 Links
Evolved to offer more efficiency with less maintenance and less noise, the Super Narrow HG-X11 speed chain offers a smooth and reliable shifting performance as you would expect.
Shimano Ultegra Di2 R8050 Front Derailleur
The new FD-R8050 is redesigned to fit a wider gear pitch without sacrificing shifting performance.
Quick and smooth front shifting is guaranteed under all circumstances, even when you’re shifting to the large chainring while riding out of the saddle. Due to Shimano Synchronized Shift the front derailleur will shift automatically when the rear derailleur is shifted, allowing both derailleurs to work together efficiently. With Semi-Synchronized Shift it’s the other way around, with the rear derailleur shifting automatically when the front derailleur is shifted, obtaining optimal front/rear gear positioning. At the same time, Di2’s auto-trim feature will automatically centre the front derailleur precisely around the chain, avoiding chain rub as you move the chain across the cassette. This is how fast, precise and smooth your shifting can be.
Shimano Ultegra Di2 R8050 Rear Derailleur (Choose from Short Cage and Medium Cage)
The Shimano Ultegra Di2 R8050 Rear Derailleur 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.
Shimano Ultegra Di2 R8050 Shifter Set
The new Shimano Ultegra Di2 R8050 Shifter Set dual-control lever allows for more intuitive shifting.
A clearer separation between the shift buttons ensures precise shifting, even when wearing thicker gloves. Each switch can be used for multi-shift ON or OFF and top hood buttons can be programmed to control third-party devices. All functions can be customized through the Shimano E-Tube app or PC software.
