Great part to slide the valve stem through a small hole in the rim that looks smaller than the stem when you are trying to push it through. I couldn't do it with one hand, and I don't have many hands either. So I bought this item and was able to do it. It still requires a bit of tweaking and tension, but that's why this grip and steel cable is as strong as it gets. As my title suggests, this tool makes the "impossible" possible with little effort.
