Shimano Ultegra Di2 ST-6770 STI
The electronic Ultegra Di2 Dual Control Levers for 2x10 speed have an improved ergonomic shape. The Dual Control Levers show the importance of state-of-the-art technology with regard to performance enhancing design. A better access to the brake lever from the upper side gives smooth braking operation with a closer pivot. This results in better controllabillity for more aggressive riding style under severe conditions. 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.
