The Shimano Ultegra 6770 Di2 electronic change arrives
Professional racers have been using the electronically powered Shimano Dura-Ace Di2 groupset at the world's biggest races for the past four years. The highest mountains, the most extreme weather conditions and the worst tracks and roads in the cyclocross world have been his test bed.
Now, Shimano has decided to introduce this revolutionary technology into the Ultegra groupset, making it available to a much broader group of cyclists and cyclists.
The advantages of Di2 (Digital Integrated Intelligence) technology are more than evident to the public that has had the opportunity to test it: gear changing becomes easier, effortless and fast with the touch of the buttons. Additional benefits include automatic front derailleur adjustment, unrivaled precision, and easy installation.
The new group Shimano Ultegra 6770 Di2 It will consist of Dual Control levers, front and rear derailleur and battery. For the rest of the components, the Hollowtech II cranks, brake calipers, cassette and chain from the Ultegra 6700 group will be used.
The electrical system consists of only two cables (the Dura-Ace Di2 has four) and in this case the connectors are smaller. Easy to connect, it will be available in different lengths to fit most frames.
The Shimano Ultegra 6770 Di2 groupset incorporates the SEIS (Shimano Electronic Intelligence System) system, based on the SIS (Shimano Index System) system that has widely proven its superiority in gear shifting over the years. The big difference in this case is that the gear change is generated by electronics instead of mechanics.
