My 79 Schwinn LeTour, Chicago built, seems to have had just a little better frame work. I was just talking to a friend, who was a Schwinn LBS back in the day, and he was mentioning how BAD the last few years of Schwinn were. They often had to rebuild the brand new Schwinns before they sold them, THAT was what THEIR customers deserved in a NEW bike. NOT a pile of mismatched parts, misaligned bits, Wrongly assembled parts...just a nightmare.
