With this Shimano Ultegra Di2 front derailleur board your ride, 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 Synchronised Shift, the front derailleur will shift automatically when the rear derailleur is shifted, allowing both of your road bike's Shimano Di2 derailleurs to work together efficiently. Customisable Electronic Shifting With the Semi- Synchronised Shift feature that’s also on the Shimano Ultegra Di2 R8050 front derailleur, it’s the other way around. The rear derailleur shifts 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.
Specifically designed for road cycling, the Shimano Ultegra R8000 front derailleur features an updated link construction and an integrated cable tensioner for lighter front shifting operation and easier setup. Another highlight is it flawlessly moves your chain up and down, without extra effort. The result is a shift that is precise and direct, with no delay. It also matches the wider pitch of Shimano's R8000 chainset, creating increased compatibility with disc brake road frames.
