It has taken me decades of doing bike service, commercially and as a hobby, to become completely convinced that Campagnolo shifting gear is crippled junk. They've been playing catch-up with Shimano since SIS appeared, but they haven't caught up yet.

You can use a Wolf Tooth RoadLink as a prosthesis to make Campy junk slightly less crippled. I put one on my e-bike so it can cope with the 16-40 cassette and 14-38 freewheel I use.
