Hi again,

Well, this could be a nice little project. So, now that I have good info on the compatibility of the chainring, what about the freewheel?

I now have a 5 speed free wheel. Shimano z 14/32. Can this be replaced by any 5 speed freewheel? Is this doable (yes these are just listings from ebay):
Shimano MF-Z015 5sp SIS Freewheel 14-28T
Shimano Freewheel SIS 5spd 14-28 gold

And, a new chain. Well, is a chain, a chain? I assume that I need a particular size/length...

Mike
