I'm experiencing chain rub. The drive train is Campy Record from 1984, two chain rings, six cogs. The outer edge of the chain (which I had to replace) rubs against the inside walls of the front dérailleur cage when in the first and sixth cog. It doesn't matter which chain ring I'm in. I can trim out the rub using the front dérailleur lever, but I can't believe that should be the norm. I've tried adjusting the inner and outer limit screws on the front dérailleur to no avail. Could the chain be too wide? Does a Campy drive train require a special (Campy?) chain? What's going on here?
