I bought this bike in late 1980's from a bike mechanic in East Providence, RI. He had just powder coated the frame flat black, and rebuilt it with Shimano Deore derailleurs. I'm not sure of year since serial numbers are not visible on BB. Plan to sell it as I moved to a 3rd floor condo with no elevator and bought a lighter road bike that is easier to tote (I'm 71). Any help you can provide to help me sell this is very much appreciated. Thanks.
