Feedback Sports' Wheel Truing Stand is a simple and effective solution to truing wheels, plus it can be mounted to their work stands -- perfect for those on the go. One problem, however, is it requires quick-release wheels to work. These Wheel Adapters fix that little hiccup. They come in 12mm, 15mm, and 20mm diameters so you can use the Feedback Sports truing stand with all current mountain bike standards.
