Shimano Ultegra Di2 6770 10sp STI Shifters
Professional riders have been using the Shimano Dura-Ace components with Di2 electronic shifting technology in the biggest races in the world over the past four years: over the highest mountains, in the most extreme weather conditions and over the worst possible roads and cyclo cross tracks.
Now it is time to introduce this revolutionary technology into the Shimano Ultegra, making it available to a much wider group of road racers and enthusiasts.
The advantages of Di2 (Digital Integrated Intelligence) are clear for everybody who has tested it: changing gears becomes easier, effortless and faster by simply touching the shift buttons. Control at the top of your fingers.
Additional benefits include an automatic trimming front derailleur, unmatched precision plus super easy installation and adjustment. Shimano Ultegra 6770 series with Di2 technology consists of Dual Control Levers, electronically operated front and rear derailleurs, a battery and electric cables. The electric cables include only two core wires (DURA-ACE Di2 has four) and the connectors are smaller too with a diameter of 5.1mm (-3.7mm compared to DURAACE Di2).
Easy plug and play system to connect the cables, Connection with PC for diagnosis and changing the shifting order. The SEIS (Shimano Electronic Intelligence System) is based on the Shimano Index System (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics.
Ergonomic STI levers knows just how much control they have over all components. 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. ST-6770 Dual Control Levers (10-speed, for double cranksets) Effortless electronic push button shifting Intuitive operation, similar to mechanical ULTEGRA Reach adjust mechanism - fits all hand sizes.
Weight: 313g/pair. Not compatible with DURA-ACE Di2.

Shimano are a Japanese manufacturer primarily known for their cycling components, and to a lesser extent shoes and clothing. Founded in 1921, Shimano is widely believed to be the largest cycling component manufacturer in the world, having reached this status through a combination of innovation, reliability and value for money. Whatever your style of riding, whether it be road or MTB, Shimano will have a component range to suit your level and budget, from the low end Alivio and Tiagra to the professional standard XTR and Dura-Ace. Over the years, Shimano have revolutionised bicycle gear, brake and pedal systems, such as the recessed SPD, Hollowtech crank arms and smooth shifting Hyperglide sprockets. Initially their component range faced competition from Suntour, whereas nowadays their primary rivals for market share are SRAM and Campagnolo.
