Both work perfectly with our 40 mm or 70 mm Caffélatex Tubeless Valves.
Caffélatex Valve Extension is externally threaded, so that it’s possible to secure the valve to the rim and achieve air-tightness in tubeless applications. The ability of these extensions to be tightened is a plus in general, making them stable and silent also in non-tubeless applications. They can be used with any RVC (replaceable valve core) Presta valve.
With a nickel-plated brass body, Caffélatex Valve Extension is produced with extremely tight tolerances, to guarantee perfect, leak-free functioning.
