Attention Luggage Screener!
Not only can Mark V outpack me, and has traveled with his bike like ten thousand more times than me, but he’s got this pictogram in his S&S case as an anti-TSA device. I’ve formally requested a copy. It illustrates to the person opening the case in some dank airport basement somewhere, how to reassemble the case with the compression members intact. The two disks and a piece of plastic pipe are also known as the pizza box things (from the plastic thingies that prevent the box lid from smashing your pie).
