Shimano FD-R8050 Ultegra Di2 11 Speed E-Tube Front Mech

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

Full and semi synchronized shifting programable, Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences. Semi synchronized shifting means when a front shift is made the rear mech will automatically correct to the appropriate ratio

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

Designed to work with the wider gear pitch spacing Shimano chainsets without sacrificing shifting performance on bikes with 135 / 142 mm O.L.D.

Cable tension is adjustable on the front derailleur

Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available
