I am rebuilding a 1977 Fuji S-10-S. I love to ride old steel as I like the feel and general give of the frame. I want to use a group set from the same vintage but desire something that is much better than the Suntour Honor/GT set that came on the bike. I have a Suntour Seven set that I may be able to use but would prefer better quality. What should I aim for when assembling the parts for this bike? Yes, I know the freewheel and chain will need to be new, or NOS if possible.
