The Clik Valve system makes inflating bicycle tires easier than ever before by simply replacing your existing presta valve cores combined with a matching Clik Valve Pump Head or Pump Head adapter. Minimal effort is needed - thanks to the intuitive click system that creates a secure connection between the pump head and valve. The Clik Valve design greatly reduces risk of air loss during the inflation process and minimizes wear on the pump head itself.
