'89 or '90 Sport DLX. I bought it new in the summer of '90 or '91 and I know it was the previous year's model at that time. I dunno, I guess it could be even older. Shimano Exage components. Tange Infinity CR-MO frame. Hi-Ten fork. Looks like it says ACS on the hubs.
Even though I was a very active cyclist when I bought this bike, I don't really know the terminology or what else I should mention. Would be glad to edit this post and add anything anyone wants to know.
I can't wait to get out and take it for a nice long ride again.
Definitely older than 1990, as that is when the brand name changed to Diamondback. Offhand, I'd say very late 1980s.
