I made the mistake of having my late 1970s Cuevas road frame refurbished and then putting a modern drive train on it. The bike just does't have the feel I remember as a young rider (maybe it's my age). So I'm committed now to cleaning up the original Zeus parts. I have two sets from two Zeus-equipped bikes I had in my late teens and early 20s.
Questions: Where can I get chainrings that fit the crank bolt patters; are there any precautions when dealing with bearing races; and is this just a fool's errand? Any help/advice would be helpful, as I am new to finding old parts in a new world.
