Valves come in a number of variations. Sometimes the tire has a different valve as a pump, we have adapter valves for this. Sometimes you need a little more length to reach it properly, we have extension valves for that.
We recognize 3 valve types:
AV = Auto valve also known as Schrader valve or American valve
DV = Bicycle valve also known as Woods valve, Dunlop valve or Blitz valve
FV = French valve also known as Presta valve or Sclaverand valve
