The Shimano FD-M8070 Di2 Double Front Derailleur, for 34-38T XT Di2 Dyna-Sys 11-speed front derailleurs operation is pioneering, smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. Whats 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 no matter what the conditions
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 trail ahead
Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences
