Modular Valve System

The Maxxis Modular Valve System allows you to easily customise your bike and save weight at the same time.

  • Removable valve core
  • For use with MVS Tube or Maxxis tubular tyres only
  • Available in Presta valve stem lengths of 48mm, 60mm, 80mm and 100mm
  • Choose a specific valve length and colour, without resorting to finicky valve extensions
  • When the tube needs to be replaced, the valve stem transfers to the new tube
