Shimano Ultegra Di2 ST-R8060 STI

The Shimano Ultegra Di2 ST-R8060 dual control levers for triathlon and/or time trial allow intuitive shifting operations while their aerodynamic design reduces drag. To make the design smaller and shorter a switch box like on the predecessor ST-6871 was a eliminated. The integrated button on the side of the body works just with the Synchronized Shift technology which.



Shimano Dura Ace Di2 SW-R9160 bar end shifter

The electronic Shimano Dura Ace Di2 SW-R9160 bar-end shifter is especially designed for time trial and triathlon bars. The remote shifter features an incredibly low-profile design with a redesigned switch optimized for hand positioning on the extensions. So it is easy to push the thumb switch when gripping the top of the TT extension what makes a direct, fast and precise shifting possible. The one-button operation minimizes movement and maximizes the aerodynamic efficiency.



Shimano Ultegra BR-R8000 brake caliper

The BR-R8000 brake caliper 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 FC-R8000 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.



Shimano Ultegra Di2 FD-R8050 front derailleur

The FD-R8050 front derailleur 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 RD-R8050 rear derailleur

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 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. To meet the driver's preferences, the Ultegra CS-R8000 cassette offers a variety of high-performance gear combinations. Compatible to HG-EV and HG-X 11-speed chains.



Shimano CN-HG701-11 chain

The super narrow HG-X 11-speed chain features an efficient, quiet and low-maintenance design for smooth and reliable shifting performance. Thanks to additional reinforcements also suitable for E-Bike use. Last but not least it features the proven SIL-TEC coating.



Shimano SM-JC41 junction box

Junction box for Shimano EW-SD50 Di2 wires (sold separately) with internal routing. It connects front and rear derailleur, cockpit area and battery. Only for use in compatible frames.



Shimano EW-RS910 Di2 junction

The EW-RS910 can be installed in the bar-end or in the frame. It offers an interface for charging the battery and a charging indicator. With the button of the EW-RS910 and the X and Y switches of the STI, the front and rear derailleur can be adjusted.




Note:
In order to ensure proper functioning of the electronic Di2 drive system, all components require the same firmware version. 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.
