Ok, I just talked to the guy selling it, and my speculation is correct. Seen only pavement or dirtroad (in campgrounds). He is the original owner and after more research I am leaning toward it being aluminum frame. It has pavement minded tires on it and he does have the knobbys that came with it. He is also the original owner and he said it is a '97 or '98. Now providing it is in as good of condition as described, is it worth the $250 he is asking? My only concern is it being 9 or 10 years old.
