Serial number is AA, so does that mean it’s an 83? I couldn’t find initials on the nds dropout. The superbe tech RD is in immaculate shape under a layer of grime. I’m getting more and more excited about this bike. The wheels look nice. The Suntour sealed hubs have been excellent in my past experience. I’ve never had Super champion rims. I assume Wolber had bought them out at this point.

Can you explain what you mean about wide section rims?
