The last generation Super Record does better and was changed to swing the 7 and 8 speed blocks. The Nuovo Record was not, 6 at the rear with normal spacing.
+1, it is ALL about the freewheel. I was originally using a wide range ATOM freewheel with my Campy NR equipment and it was absolutely terrible. I switched in a tighter 6 speed Suntour freewheel and a Sram chain and it made a huge improvement. At this point I would say it is my smoothest, quietest vintage setup... and that includes Suntour Cyclone and nice Japanese parts of the day.
