Range for 70's Campy Nuovo Rec ?

What's the range that a Campy Nuovo Record rear can handle for
sprocket
and tooth difference at the front ? Does it typically have enough
horizontal throw to handle a 7 speed freewheel ?

Do the fronts have enough horizontal throw to handle a triple ?

Thanks,

I use one on a 50/40/30 and a 13-23 freewheel but it'll go to a 26 in
the back.

I bet you don't use the 50-23 or the 30-13 gears too often. that's a
30T difference in chain wrap, and the best GT derailleurs are spec'ed
to handle 34T ... Either that or you've got a hot-rodded nuovo record
with a long cage (such derailleurs exist and campy USA actually
recommended such mods in their newsletters.)

Sorry, Don, dead stock. And I don't use the extremes.

And they also sold the Rally, which was a spectacular POS for the
money. I used an '80 Rally cage on a NR derailleur in a fit of
mixing and matching and it was about half as good as a $12
Suntour. I used a NR front derailleur for a triple with no
problem -- however, it was a Campy triple with a small ring in
the 30t range (a drill-and- tap after-market bolt on and not the
model that was available on a limited basis in the late '70s.) --
