Has anyone managed to run shimano 11 speed sit drop bar shifters with 10 speed rear mechs on an 11 speed cassette?
Anyone done this with Campy Shifters?

Forget about using Dura-Ace 7900 derailleurs with 11-speed levers. The derailleur’s shift-activation ratio is different for Shimano 11-speed rear derailleurs than it is for Shimano 10-speed rear derailleurs. Furthermore, Shimano 10-speed mountain and road rear derailleurs have different actuation ratios from each other, and the same goes for Shimano 11-speed mountain and road rear derailleurs. Prior to road 11-speed and mountain 10-speed, things were simpler; Shimano road rear derailleurs up through 10-speed and mountain-bike rear derailleurs through 9-speed all have the same activation ratio.And your intuition is correct that a Shimano 11-speed shifter will not work well with a 10-speed front derailleur because the 11-speed shifter is designed to actuate the longer lever arm of Shimano 11-speed front derailleurs

shimano are going to run out of actuation ratios soon and will accidentally create a 13 speed system that will work with 6 spd road mech and a 7 spd mtb mechThe derailleur’s shift-activation ratio is different for Shimano 11-speed rear derailleurs than it is for Shimano 10-speed rear derailleurs. Furthermore, Shimano 10-speed mountain and road rear derailleurs have different actuation ratios from each other, and the same goes for Shimano 11-speed mountain and road rear derailleurs.
and yeah the tourers will rejoice

Dirty rider Im not so sure about your post as I'm running Ultegra 6800 shifters with a 5700 front mech without issues?
