Hey, if it’s from 1983 then the rear spacing will be 126mm. It’s possible that the frame won’t accommodate 11 speed drivetrain without respacing. My road bike which is 126mm as well works well with Campy 11 without respacing but on the other hand my tourer (Koga-Miyata as well) wouldn’t work with anything more the 7 speed. Might be worth checking out before committing to a 11 speed setup.
