Shimano Dura-Ace Di2 ST-9070
The electronic shifting logic is nearly the same as the Shimano mechanical system. There is no need to rethink - simply press the button. With a reach adjustment mechanism the Dual Control Levers can be adjusted to the rider in order to better accommodate smaller hands and a wider assortment of bar bends. The hoods have an ergonomic design for increased comfort, even on long distance rides.
The shifters feature integrated buttons on top of the hoods to operate the new wireless FlightDeck computer without the need to take the hands of the handlebar.
The Dual Control Levers are mounted on the handlebar with a titanium fixing band and a titanium bolt to reduce weight. An optional satellite switch allows shifting from any position of the handlebar.
