Brand new - Did not use

The Shimano Dura-Ace Di2 group delivers shifting performance like none other. Seriously, this setup is awesome. With electronic shifting you get smooth, precise shifts with instant engagement, no matter what the riding conditions are like. These shifters use electronic touch pads to give you more rapid action with a lighter feel. They also have carbon lever blades to help shed every last gram possible.
Electronic touch pads transmit shift data to the derailleurs rapidly for up to 30% faster shifting than with cable systems
Ergonomically shaped hoods and bracket design keep your hands comfortable even on long rides
Slim carbon brake levers and titanium fixing hand and bolt help lighten the overall weight
New pivot location for the brake lever improves modulation and gives you a more comfortable grip
Reach-adjust feature lets you tune these levers for smaller hands

Weight: 255 g./pair
10-spd compatible

By using unidirectional carbon fiber brake lever blades and eliminating all of the mechanical shifter parts, the new Dual Control lever weight is reduced by over 155g over the mechanical version. The ergonomics are slimmed down and further refined for a comfortable grip.
