Description:
Front derailleur: The front derailleur's operation is pioneering. Smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur. This ensures that the chain never rubs. Its rigid construction guarantees swift, silent, smooth shifting even under the most demanding of conditions.
Rear derailleur: The rear derailleur is pre-programmed allowing you to shift gear quickly and accurately in all conditions. The derailleur is immune to rough circumstances and protected from impact damage by its reinforced inner cage. It has a maximum sprocket of 28T for wide-range gearing.
STi Shifters: With Di2 technology, shifting is even easier and more 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. Shimano riders will be used to them immediately since all the buttons are in the same place as on regular levers. The distance between the lever and the handlebar is adjustable. This makes it extremely easy to brake and shift even for riders with smaller hands.
Battery, Charger and Power Lead: The power house of Dura-Ace (7970) and Ultegra (6770) Di2 is a long-life 7.4V Li-Ion battery that is both compact and reliable, taking shifting effort away from you. One charge can give between 1000 and 2000 kilometre range depending on conditions and front mech operation (as this is the main power drain). The charger, with lead, will get your Di2 battery fully charged when it's low on power.
