Seems I need a new chain. I have a Colnago Super w/ an early 80s campy super record rear der no front der. 2 chainrings and 5 speed freewheel = 10 gears. I can't figure out what chain to get. Ideally I can pick from these because I get a deal on them: http://freewheelbike.com/page.cfm?Pa...=items%2Eprice
Does the KMC z50 work? It says 6-8.
If nothing there works for cheap, is there something on the net I should try?
