Where the bottom bracket shell construction is electro forged and then the chain stays, down tube and seat tube are EF to the bottom bracket.

WE only live once, or so they say!!!
Is this an O.G. paint or a repaint? Any way I still like your bike. I'm dealing on a twin bar. Hope to have it by the end the wek. Enjoy the ride. Razin.

This was a manufacturing process specific to Schwinn frames of a certain era. I’m probably going to botch this, but essentially they are connecting the tubing by creating an arc between one positively charged tube, and one negatively charged one, versus fillet brazing, which was the standard at the time.
