• How about if I wanted 1x11?

    How about if I wanted XTR mech?

    Both fine. They'll work with anything Di2 except the original 4 wire 7970. They'll even work with Alfine Di2 if you're that way inclined.

  • Thought latest firmware needed an 11 speed front mech for the 6770 levers to work 11 speed. Does it just mean that it wont work 11 speed if you're still trying to use the 10 speed FD and that without one at all, 11s works fine?

    Not sure I can be bothered with this after looking at the price of batteries...
