When building up my latest project, a '76 Jack Taylor, I discovered that my plan to use an NR front derailleur was not going to work with the 52/44/28 crankset as the cage is just not long enough. I had used it with a 52/47/36 in the past but maybe that is the limit (unless you go to a smaller big ring). Since I planned on using Suntour Barcons and Suntour freewheel I was thinking that I might as well use period Suntour derailleurs as well. I have 3 or 4 V-GT and V-GT Luxe rear derailleurs and they do shift nicely but other than that I really don't have much experience with vintage Japanese components. What would be a good Suntour front derailleur to look for to match the V-GT rear, perhaps a "7", a "Compe-V", or "SL"? Further questions:
1. Did all Suntour front dr's of the era ('75 to '80) use the funky pull for low scheme?
2. Did they all have adequate throw for a triple crankset?
3. Are the cages longer than the NR to allow the 28T chainring to be used without chain drag?
