Rider noticed poor handling. On examination, the seat tube was broken through. There was another frame noise that may have masked frame-break noises.

Service history unknown, but ridden vigorously in Colorado (hilly).

This joint is a (comparatively) common place for failure, including steel frames. This particular failure is in the heat-affected zone of the weld. Some frames use gussets here to better spread the load. It is not known if the tube was butted.
