Great value high performance 105 double Di2 front derailleur
The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to wireless communication with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur
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 that connect to the battery not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts
Wireless connection to the shifters
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.
Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available
