Let me know if there’s anything else you guys need to find out the model!!! Thanks for the help! Would it be worth fixing up? Bought a while ago but now I need a new bike!
Welcome to the forums. The subject bicycle is a very good match for a 1980 Schwinn Continental. If not for the presence of the Schwinn name, these would be considered a very low end bicycle, on par with department store bicycles. They are extremely heavy and poor performing for the era. I'd be looking for something else. It's pretty easy and not too expensive to find something 8-10 pounds lighter and better performing.
