\n\t\tWith Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear. The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts.
\n\t\t
\n\t\tSimply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold. Climbing twin button satellite shift switch is used to operate the rear derailleur whilst your hands are on the top of the bars, one button up, one button down.
