The Stan's No Tubes 44mm Valve Stem Pair is the perfect accessory for your tubeless tires. Although tubeless set-ups remove tubes entirely from the equation, you'll still need valve stems to seal the rim/tire interface from losing air, as well as provide a method for tire inflation and sealant injection. That's where Stan's No Tubes 44mm Valve Stem Pair comes into play. These 44-millimeter valve stems feature a removable valve core for injecting sealant into your tubeless set-up without dealing with the hassle of breaking your tire's bead. You'll find they work equally well with UST, Road Tubeless, and standard tube-type rims, thanks to their universal shape and rubber cone along the end opposite of the valve.
