compatibilité avec le DI2 6770

This DOES work. I have just done it. One thing is vital; all components must have the latest firmware update and must be configured to 'talk' as a system. This is something your local bike shop can do for you. My LBS did it free of charge.
Generally speaking, all the electronic components are compatible between the Ultegra 6770 and the Dura-Ace 9070 systems [except the Sprint Shifters]. This means that all of the road bike Ultegra/Duar-Ace dual control brake levers/shifts, time trial shifters, and climbing shifters can be used with either Ultegra 6770 or Dura-Ace 9070 front and rear derailleurs. Any of the Ultegra/Dura-Ace controllers (A Junctions) can be used with either system. All components use the same cables and connectors.
Thus, an Ultegra 6770 10-speed system can be converted to 11-speeds by replacing the RD-6770 with the Ultegra RD-6870 or Dura-Ace RD-9070 11-speed Rear Derailleur. None of the other electronic hardware components need to be upgraded. However, an 11-speed compatible rear wheel, sprocket hub body, sprockets, and chain will be required. Firmware will need to be upgraded.
Hope this helps.
