So would we! Please post the brand and models of the compoents. Any tubing decals on the frame? Pics would help. Components are most likely Shimano or SunTour and if so should have two letter date codes on the back. Component date codes, provided the parts are original, are usually the same year or one year older than the frame. This will give you a good idea of the vintage. The keys for the codes can be found at http://www.vintage-trek.com/component_dates.htm .
