The Shimano Ultegra 6770 Di2 electronic change arrives
Professional riders have been using the Shimano Dura-Ace Di2 group, with electronic technology, in the most important races in the world in the last four years. The highest mountains, the most extreme weather conditions and the worst tracks and paths in the cyclocross world have been its test bed.
Now, Shimano has decided to introduce this revolutionary technology into the Ultegra group, making it available to a much wider group of cyclists and cyclists.
The advantages of the Di2 (Digital Integrated Intelligence) technology are more than evident to the public that has had the opportunity to try it: changing gears is made easier, effortless and quickly by just touching the buttons. Additional benefits include automatic front derailleur adjustment, unrivaled precision, and very simple installation.
The new group Shimano Ultegra 6770 Di2 It will be composed of Dual Control levers, front and rear derailleur and battery. For the rest of the components, the Hollowtech II connecting rods, brake calipers, cassette and chain of 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 of the frames.
The Shimano Ultegra 6770 Di2 group incorporates the SEIS system (Shimano Electronic Intelligence System), based on the SIS system (Shimano Index System) that has amply demonstrated its superiority in shifting gears over the years. The big difference in this case is that the gear change is generated by the electronics instead of the mechanics.
Available only in bright gray, the Ultegra 6770 Di2 group is not compatible with the Dura-Ace Di2 and will hit stores in September of 2011.
