Shimano Dura-Ace Di2 TT Switch Set

Shimano Dura-Ace Di2 TT Switch Set

The most advanced level of shifting technology: at the touch of a switch Dura-Ace Di2 is quick shifting, smooth, and effortless.

• 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
• Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold
• Shift switches to be used in conjunction with ST-7971 TT aero levers which can be located on the aero extensions as a replacement for traditional mechanical bar end shifters
• These switches now give the added option of being able to operate the gears from either the aero extension or the aero ST-7971 brake lever previously not possible on a TT set up
• These Di2 switches are also compatible with the FlightDeck computer (SC-7900), measuring important data such as heart rate, altitude, cadence, gear position, battery indicator, and more
• Switches are supplied without electrical cables, as these need to be ordered separately to suit
