Since no one else responded, I'll take a shot at it. Well, you certainly live in the right area of the country to own a Ross. By now I'm sure you realize, Ross' old headquarters were right down the road from you in Allentown. There are a number of other threads about Ross that you can find using the search function. Ross made some decent bikes in addition to the low end bikes they made. I've seen the Professional mentioned by some others as a good bike. The best road bikes Ross made were called the Signature series and were produced in the mid 80's. The low end Signature series bikes have triple butted, Ishiwata frames. Other than the Signature series, Ross doesn't get a lot of respect.
Do you have anything you can share about the bike, like the type of tubing used or the componenets?
