The QuickStem Push-in Valve Stem from Hardline is an excellent option to store in a toolbox or tool pouch for a quick and permanent fix to flats while out on the trail or in the streets. Features a rubber grommet that expands when tightened to more than a third of the rim hole to prevent popping out. Simple 60 second install, no need to break the bead or remove the tire to install; just push in, tighten the nut and inflate.
