I think I have a '96. There is only a single, large tube joining the seat stays to the seat tube though. I've not seen a picture of one with this feature. I've also noticed that the down tube is oval, being taller than wide where it joins the head tube, and wider than it is tall where it joins the bottom bracket. It also has a bit of a ledge on the fork dropouts which serve to hold the front wheel on, even if the quick release comes unsprung. Does yours have either of these features?
