Want the best permanent valve stem on the market? Our Ultimate Valve System is it!

It is a full 1/2" shorter than our original Permanent Valves, lowering the risk that it will contact hazards on the trail. If it does, the high strength will further protect you against a valve stem break.

Heavy duty valve for harsh operating conditions!
