I'm considering a 1x drivetrain for a gravel bike. Shimano hasn't yet released a road/gravel solution to the market that incorporates a rear derailleur with a "clutch" (that keeps the chain from bouncing as much). Except for some of their mountain derailleurs, e.g. SLX.
So my question is, is such an 11 speed Shimano derailleur compatible (i.e. same "pull" as) their 11 speed STI shifters (such as Ultegra 6800)?
I did find an answer for 9 speed Shimano, indicating compatibility, but I'd like to know about 11 speed.
