Shimano Ultegra Di2 FD-R8050 front derailleur braze on socket

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.

The new Ultegra R8000 series is taking our rider-tuned philosophy to the next level, with an extensive range of components for mechanical shifting, electronic shifting (Di2) and time trial / triathlon.

Di2
The power and precision of Di2 is unmatched. It enables beautifully smooth shifting both front and rear. The lack of maintenance and adjustment is impressive: once you’ve customized your Di2 to shift to your preferences, it will continue to do so endlessly.

E-TUBE
change all Di2 functions and operations through the shifter buttons behind the brake levers, the top hood buttons or satellite buttons for TT/Triathlon, sprinting and climbing. You can easily customize shift speed, multi-shift options and Synchro Shift. You can also reprogram the top hood buttons to control third party-devices, for example to scroll through bike computer menus. The functionality on third-party computers also allows you to display Di2 system information, such as battery level and the gear you’re in.
