The Performance was Klein first "affordable' frameset. It made it's debut in 1983 but was underpriced by Cannondale's frame, which made it's debut the same year. Versions of the Performance were produced until at least 1992. I believe the 1993 replacement was the Pinnache. Pics may help narrowing things down. Alternately, you can try dating the components using the date code info on the Components Dates page of the Vintage-Trek website, though there is always a possibility that some or all of the components may be replacements.
