I run Campy 10 on everything. I don’t race and really don’t see the need for 11 or 12. And the old 10 is so pretty anyway. To get around the gearing with the chainrings at 53/39, I’ve dropped in medium cage rear derailleurs with all my bikes. That gets me into to 13/29 and 12/30 rear cassettes. Solves the issues for hills. The all steel cassettes can be had for 50 bucks, so I’ve got a shelf full of ‘em now. The more people move to the 11’s or 12’s, the more 10 for me on the cheap.
