Shimano (Cycling) ULTEGRA FD-R8050 Front Derailleur 2x11 Speed (Direct mount)

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 shift
