The Maxxis Modular Valve System (MVS) allows you to easily customize your bike, and save weight at the same time. The separation of the tube and the valve stem allows you to choose a specific valve length and color, without resorting to finicky valve extensions. When the tube needs to be replaced, the valve stem transfers to the new tube. MVS tubes MUST be used with MVS valve stems.
