Tony, you could probably take the serial number to a local Trek dealer and they might be able to tell you the exact model year. Mine was black in color, with bonded aluminum and lugs. It did have a cro moly fork though. I don't remember exactly but I think the lack of clearance was with the seat tube in the back or maybe it was the brake hanger up top, how's that for lack of memory. They were some of Treks earlier aluminum bikes and they bonded or glued the lugs which held the tubes. Supposedly it was a rare problem when one of the bonds failed according to Trek but I do know that imo, my bike's ride was terribly harsh and forever "rattled". Best of luck.
