Why does the Psiclops use straight instead of angled quick-chucks?
A. Angled chucks tend to rotate clockwise or counter-clockwise after they are connected to the valve stem. This causes the chuck to loosen and allows air to leak uncontrolled from the tire. Our straight chucks won’t twist and leak, but they won’t work on every type of wheel on the market either. It’s our goal to provide the most accurate, quality tools possible. Unfortunately, to do so means we can’t help everyone.
