Employing the latest technologies from elite Dura Ace R9100 road components and through its proven System Engineering approach, Shimano’s Ultegra R8000 series delivers refined rider ergonomics, increased shifting performance and confident control in all riding conditions. Riders who choose the Di2 shifting components (R8050) have further the possibility to turn on or off the multi-shift function as well as to customize every key's setting individually.


Shimano Ultegra Di2 ST-R8070 STI

The Ultegra Di2 ST-R8070 dual control levers allow not only more intuitive shifting operations but also quick and precise shifting thanks to a clearer separation between shift buttons. A more defined click feeling and a wider reach adjustment range generate even more comfort. Group specific each switch has the option for multi-shift ON or OFF. The STI's top button remote switch is programmable for third party cycle computers. Every function is compatible to E-Tube application or Shimano PC software.

The Ultegra Di2 dual control levers in hydraulic disc version improve rider control in all conditions. The small bracket size feels great on the palms and improves the ergonomics. On top of that lightweight materials make the STI's race-ready.

Shimano Ultegra BR-R8070 hydraulic Flat Mount caliper

The hydraulic Ultegra BR-R8070 provides the next stage of rider control in all conditions. Utilizing a lightweight and minimalistic Flat Mount design, the sleek caliper integrates seamlessly into a road bike's aero profile where it can be installed directly at frame or fork. The SM-RT800 rotor (optional) offers even greater heat management capability than Shimano's industry-leading ICE TECH Freeza rotors, resulting in unparalleled braking performance and reliability in the most demanding conditions.

Shimano Ultegra FC-R8000 crankset

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 cranksets with 50-34, 52-36 and 53-39 teeth are weight-saving thanks to Hollowglide technology and the outer chainring made of aluminium/CFRP. Alternatively, the cyclocross crank is offered with 46-36 teeth.

Shimano Ultegra Di2 FD-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.

Compatible chain type: HG-EV 11-speed/ HG-X11
Chain stay angle: 61-66°

Shimano Ultegra Di2 RD-R8050-SS rear derailleur - short

The Shimano Ultegra Di2 RD-R8050-SS rear derailleur features the group-specific sleek integrated appearance with a low-profile design. An optimized slant angle and a wide range from 11 to 30 teeth regarding compatibility are further assets of the Di2 Shadow rear derailleur. Thanks to an intuitive shift control the thr rider can maintain his race concentration. For an optimal setting at any time rear derailleur's system communicates with front derailleur via Synchronized Shift technology.

Shimano Ultegra CS-R8000 cassette

Superior choice is at the heart of Shimano's rider-tuned philosophy. With gear combinations 11-25T, 11-28T, 11-30T, 11-32T, 12-25T and 14-28T you’ll have all the options you need to tune your ride.
