Shimano RD-R7150 105 Di2 12 Speed Front Derailleur

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
