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.
The updated low-profile "Shadow" design of the Shimano Ultegra R8050 rear derailleur increases its shift stability and gives it a sleek and integrated appearance. Race endurance is guaranteed, through the optimised slant angle. The wide cassette compatibility of 11-25 tooth to 11-30 tooth will secure a smooth ride in even the highest and steepest mountain areas.
Compatible with a cassette tooth count range of 11-25T to 11-30T and adopting Shadow technology from Shimano's mountain bike (MTB) range, the Shimano Ultegra R8000 rear derailleur ensures a smooth ride in even the highest and steepest mountain areas. The integrated Shadow technology is race-proven and with its low profile design, this slick operating road rear derailleur is aerodynamic, more compact and fits closer to the frame, ensuring less damage in a crash.
