Not my experience. The cogs may be interchangeable, but they don't shift the same.
A couple of years back Pastor Bob and I conspired to build up a 13-24 ultra spaced 6 cog Regina CX freewheel for my all-Italian Mirella (OK, The BB is Phil Wood, but I'm working on it.). I also built up on my own an identical Atom 77 ultra spaced 6 cog 13-24. Same 13-15-17-19-21-24 progression. Both drive trains are Campy NR. I rode both bikes this week after having ridden neither of them for over a year and couldn't believe how much better the Regina shifted.
