Shimano Ultegra Di2 FD-R8050 11 Speed Front Derailleur
Redesigned to be compatible with a wider 11-speed gear range but still retaining the same slick shifting ability, the Ultegra Di2 R8050 is a real game changer. Stiff and efficient enough to change gears cleanly even when you’re pedalling hard out of the saddle, it’s the ideal front derailleur upgrade for your Shimano Ultegra Di2-equipped road bike.
Boasting the same technology as Dura-Ace models, the Shimano Ultegra Di2 R8050 Front Derailleur delivers swift, precise and quiet shifting as you power up to speed on your road bike. It also seamlessly combines with your other Shimano Di2 components.
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 Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur
- The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load
- The difference in the effort and time to actuate the shift between mechanical and Di2 is truly staggering
- The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts
- The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead
