Easton tubing was used on the 1990 model. Not that it matters really. The 1989 and 1990 bikes were almost identical, and the market value of either is going to be the same.
Around here, buyers can get an aluminum frame bike with STI shifting at the $300 price point. It would be hard to sell a 20 year old aluminum frame bike at that price, unless it was a Cannondale, especially this time of year. Buyers of vintage bikes tend to want steel frames. Buyers of more modern bikes tend to want STI shifting.
