Shimano Ultegra Di2 ST-R8050 shift/brake lever

The Shimano Ultegra Di2 ST-R8050 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.

Shimano Ultegra BR-R8000 brake caliper

The BR-R8000 offers a very sleek design, with narrower gaps between the arms. The wider clearance makes it compatible with larger tire sizes such as 28C. The stabilizer between the axles reduces deformation and improves the braking efficiency, offering a clear contact feeling with balanced rigidity, weight and stopping power.

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 and carbon fiber reinforced polymer (CFRP).

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 is 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.

chain type: HG-EV / HG-X 11-speed
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. Smooth and fast gear changes are guaranteed. For higher corrosion resistance and increased durability the sprockets are nickel-plated. Compatible to HG-X and HG-EV 11-speed chains.

Shimano CN-HG701-11 chain

Shimano 11-speed chain with SIL-TEC surface. Also suitable for e-bike.

Sil-Tec, an advanced surface plating technology to increase both performance and durability. It adds a low friction surface treatment that runs smoother and lasts longer.

The remaining junction is for the connection with SM-JC41 junction kit via separately sold EW-SD50 wire kit. For external installation. Not compatible with Flight Deck.

Shimano Di2 SM-BCR2 USB charger for SM-BTR2 + BT-DN110

Notes:

The optional diagnostic device allows for reading out or updating the firmware version. An operation of components with different firmware versions may cause a malfunction or loss of function.

Operation requires additional EW-SD50 cables. These are not in scope of delivery. Please contact our service team for a suitable configuration for your system.
