I really needed a cable but bought it because it's Milton. My primary need for this was to hold the tubular bars in the wheels of a wheelbarrow etc when fitting tires. It only flexes in one direction, so it can't just be bolted onto the stem while the stem is inside most wheels. It's probably great for installing tubeless valve stems, but I only do it every few years, and the pliers on the sacrificial valve cap always did the job. Well, now I have the right tool for it.
