Shimano Ultegra 6770 Di2 Full Groupset
Professional riders have been using the electronic Di2 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 to 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
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 Dura Ace Di2). Easy plug and play system to connect the cables, which are available in different lengths to accommodate most frame dimensions. Connection with PC for diagnosis and changing from conventional to inverse shifting.
