They had a pretty short model history (I own one of these odd ducks but it's hanging from rafters) according to some just from 1990 to 1993. I bought mine used so no idea when it was built but when I get a chance I'll check it's serial number. A fun bike (if you ignore a few bizarre quirks like the 1-1/4" HS and extra wide pressed-in bearings BB spindle) I dig mine...
