Jon, my 83 Super Record shifted fine onto a 28. I have an old Performance Bike Shop catalog from 1983 that lists the largest tooth capacity at 28. Don't know if that is Campy spec or not. I know the cages were different on the later Supers. Somebody with alot more Campy history would be better at explaining or shedding some more light. Naturally, I got less teeth chatter the more I pulled the wheel back in the dropouts. But it never jerked back as with derailleurs that have exceded their capacity.
