You guys got me thinking. 55 years is a long time to use a chain. I certainly got my money's worth out of it. I'm talking about the blue Legnano posted above. 2 years ago, I bought a new chain with the idea of changing my (then) 53 year old chain. Ok, today, I finally did it. You know, the new chain (Sram 8 speed ) is considerably lighter than the old motorcycle chain that came with the bike. It seems to shift better, is quieter, and provides a little more clearance between the small rear gear and frame. I recently went from 5 to standard 6 speed (not ultra 6) freewheel, and the old frame was pretty close to the chain. Better now, but I'll bet the new Sram doesn't last 55 years. 😁
