Atma-Sphere, I will never ride a bike with anything but Campy on it. That Jap stuff is cheap overweight crap. It only worked better if you did not know how to shift.@mijostyn
My current bike is a Specialized S works Diverge with Campy Super Record 12 speed EPS disc brake group. Fulcrum Carbon tubeless rims with Hutchinson Sector 32 tires. Perfect bike for an old fart with bad wrists:)
Back in the 70s Campy was heavier, shifted slower and less precisely than the alloy SunTour stuff.
I got rid of derailleurs years ago- I have a custom Reynolds 953 and a Ti frame both equipped with Rohloff hubs. The Ti frame is a Jones and despite no suspension, is the most comfortable bike I've ridden.
