I was about to start building my new thru-axle wheels, when I realized that it was going to be a pain to run the thru-axle while constantly removing and stress relieving the wheel.
These can be finicky, but the hole in the curved portion of the adapter holds the axle lightly. As you tighten the truing stand, the hub will pop into place and center itself most of the time. Great tool for a hobbyist wheelbuilder!
