Ok, just one last opinion poll before I complete the reassemble of my Raleigh Grand Sports. I bought the bike with the original Simplex derailleurs and they’ve cleaned up really nice. They appear to be in working order and everything else on the bike, except the seat, is original. I had planned on replacing the Simplex with a set of Suntour shifters and derailleurs that I have (IMO they look better and are probably more reliable), but now I’m second guessing myself and am thinking about keeping it stock.

So what’s your take: Use the Suntour or stick with the original look and functionality and put the Simplex back on?
