I'm building an 80's Ciocc San Cristobal to use as my daily rider/primary ride/commuter. The chainrings, front and rear derailleurs are period Campy super record. I'm debating on my freewheel and chain selection. Initially I intended to use a NOS Regina chain and 6sp freewheel, you know period stuff, but since I've already installed a cartridge bottom bracket and will be using later campy aero levers, I'm beginning to wonder if I might stand to gain any shifting improvements using a later-period freewheel (shimano or suntour with beveled/twisted teeth and ramps) and a newer chain. So what do you think? Stick with the period stuff? or modernize? Is the "blasphemous" act of putting these components on my bike worth the little improvement in shifting? Any freewheel or chain suggestions? Thanks!
