With 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
Single button on each side of the shift lever only works with synchronized shifting
Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold
Shifters are lightweight thanks to carbon fibre lever blades, carbon composite bracket body, and alloy expanding wedge clamp
TT / Triathlon bar STI allows shifting while braking and can be used with additional bar end switches
Brake lever pivot is positioned to be used with super SLR brake callipers
Finely tuneable reach adjusters for the levers enable custom fitment for all hands
Levers are supplied without electrical cables, as these need to be ordered separately to suit
