I rode an ‘86 for about 5 years as a commuter, lunch bike and general do-everything bike. I liked the frame a lot and felt it was worthy of better and lighter components, especially the wheels. The ride was stable, workmanship on the frame very good. I think Sheldon said the frames were common across much of the range, differences in models involved component changes. I think the largest tires I could reliably fit were 28mm though. I’ve regretted selling that bike along as it was versatile.
