I'm making a vintage fixed gear and I'm mounting an old Suntour Track cog to a Freewheel hub, locking it into place with a BB lockring. Easy enough. The cog is wider than conventional cogs- any idea on a chain size? Also, for future reference, is chain alignment critical? Finally, I know the answer shops will give, but could you use a Shimano tapered BB with a Campy crank.
