I know the components were an upgrade. The rear brake was mounted with a homemade bracket to lower it so it would work with a 700c wheel. Also the bike was repainted. Seems like someone was assembling a decent commuter. To me though, it just seems that the components should at least be worthy of the frame. The 600 group was pretty nice stuff at that time. The frame is chunky and I'm not expecting it to be something fantastic, just curious...I hoped someone would recognize the lugs or some other detail.
