We’ve released a new GlueTread Colby Valve. Here’s what’s different: The new wing nut is slimmer, making it possible to fit in tires that now tuck valve stems into the wheel for better protection. Secondly, the wing nuts are now made from CNC machined aluminum (instead of plastic) and are manufactured in our facility in Montana, keeping production close to home 🇺🇸 You can grab a replacement valve stem on our website (just $20) or in any of our comprehensive tire repair kits.
