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...
You can run any Di2 system without a front mech. If you have a rear mech and non-ancient firmware, then the FD must be from a group which has the same number of speeds as the RD, and you can't mix road and MTB FDs and RDs. Shifters are totally neutral though, except for sprint shifters.
