As above, do 10 speed shift levers work with 11 speed components as long as everything is E-tubes? Seems like it would but I don't know anyone who has tried it and I don't have 11 speed stuff kicking around. Thanks

No problem, I have used Ultegra 6770 10 speed shift levers with Ultegra 6870 11 front derailleur and Dura-ace 9070 11 rear derailleur

I did the opposite, which worked fine. I have 11-speed 9070 shiftlevers, and they work fine with 10-speed 6770 front- and rearderaileur. It works as a 10-speed gruppo though.

normally not.

but it depends on each firmware installed in every part.

If the battery internal or external mount firmware is 3.0.5 or top, front derailleur 10 speed (Ultegra 6770) does not work with rear derailleur 11 speed
