Bummer! However, I noticed that you mentioned above that you could do this. I have standard 144 BCD campy cranks and I want to add a third chainring. I've been trying to figure out what will work and also possibly keep my front NR derailleur. Here's my setup:
1981 Ron Cooper (bought new)
13-28 IRD freewheel
I'm currently running a modern triple 52-42-30 and modern triple front derailleur with an outboard bearing setup, but I want to dump it...it just doesn't look right on the Cooper. My preference is to triplize my old Campy NR crankset (approx 1972 vintage). It currently has 52-42 chainrings and I'd like to add a 30 or lower inner chainring. Thing is, I don't think the NR front derailleur can handle this big a jump. I'd be willing to drop to a 50 large ring to make this work, and I think the FD will probably handle a 50-42-30. Do you know if this would work, or could I go even lower (50-42-28?)
So, a lot of questions. Let me know if you can do this, how much you'd charge, and if Bob is still available to source the small bits that I need to make it happen. I can't send PMs because the forum requires that you have a post count above 50 to do so, which I don't have.
Thanks a lot.
I sent you a PM with my email address.
