I was given this Zeus used about 20 years ago. I haven't been riding it for a long time and am planning to get rid of it. But I have no idea of it's value anymore. Parts are Zeus 2000 and Zeus Criterium. I was told that it was of some value 20 years ago when I got it, but have no real clue at this point. I am only an occasional bike rider, and know very little on the technical end. Can anyone tell me whether it's worth putting on ebay or Craig's list,...or is really just a yard sale candidate? I have more pics if that's helpful. Thanks to anyone who can offer me any info on this!
