Shimano freewheel-freehub conversion
I'm considering upgrading my mid-80s road bike from freewheel to freehub, as I discovered today that my rear axle is slightly bent at the right-hand bearing. It has a 7-speed indexed downtube shifter, and the indexing works fine with a modern Shimano Hyperglide freewheel. My question is this: Will a 7-speed Shimano cassette be compatible with the indexing, given that the current freewheel is? I'm rebuilding the rear wheel anyway, for various reasons, so this seems as good a time as any to convert.
Thanks in advance
