The NR rear mech is the AK-47 of the cycling world. It keeps working when other rear mechs die, and was a legend in its day. That day came and went. Most NR mechs on the market now are in middling condition, with cracked pulleys being a condition of ownership. Nuovo Record and Super Record shift like Toonces the Cat drives (not very well). NR requires you to over-shift rear cogs, with greater amounts of over-shift required for smaller cog sizes. The practical lower end limit is 14T. Corncob freewheels work better than wide-ratio freewheels. I'm not the only person who has observed these limitations with the old original GS/R/NR/SR design.
Full disclosure - I've owned and managed enough Campagnolo NR, SR, Record-C stuff to know how to adjust it. I once owned an SR-equipped Colnago. I have an Ideor Asso with NR mechs in the stable right now. That bike has a Rally rear cage and is set up as a 3 x 6 triple. All of the gears work on the Ideor, just the same as all of the gears worked on the Colnago. When I ride the Ideor I expect to have to finesse the gear changes. I also expect the rear mech to resist changes from the 14T to the 13T cog. Were the bikes equipped with SunTour I would not need to compensate at all - the shifts would just occur, without drama or need for finesse.
