Hey, those look like nice bikes!
My beater started as a dark green Varsity, parked in a neighborhood front lawn with a large FREE sign taped to it. So it came home with me. The original brake pads had never even touched the rims; it just took up space for decades.
Spinning parts felt gravelly when (if) they turned. Brakes and derailleurs were frozen solid. So I went for the zero investment option, and flooded every pivot and bearing with Marvel Mystery Oil. It took a week of repeated applications, and shoving things around, but everything works smoothly now. Smells like mystery oil, but such is life.
A coworker inflicted a worn out Le Tour upon me about the same time. The only useable part (other than the frame) was the front wheel. It is aluminum, and I like being able to stop, and so that's my one performance upgrade. I have to admit, I did get carried away and tightened/trued the wheels.
It carries a steel rack with steel fold out grocery bins on the back.
The tires were on sale at the hardware store for $3 each.
The steel drops were chucked in favor of steel cruiser bars, which were outfitted with mismatched brake levers.
Safety related stuff is new; brakes, chain, tires, and tubes. It needs a front fender, but I haven't found one made of steel and junky enough in my price range yet.
It's 43.7 pounds, by the shipping scale at work. I think I'll name it Oof.
