Frame Probe

Bike Hugger gets all sorts of weird emails, spam, and photos. These photos caught my eye for the welds and the red-tipped frame probe. I have no idea what that probe is doing or what this guy is doing with the probe controller.


The email was written in French, links to this website, and I translated part of it to say, “the testing machine tridimentionelle.”

Any ideas?


Did you see one of those probes back in the day?
