Caffélatex Valve Extension (x2)

Caffélatex Valve Extension is a tubeless-specific valve extender, to adapt normal tubeless valves on higher profile rims. Incredibly reliable, it guarantees high stability and air-tightness.



  • externally threaded, for tubeless
  • very strong


Tubeless-specific, generally great:

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.

Highly reliable:

their nickel-plated brass body avoid stess failures of aluminum tubeless extensions (weakened because of the internal and external threading). Strongest valve extension for mini-pump stress-test inflation!

Available sizes:

  • 45 mm total  length (35 mm once threaded into the valve);
  • 35 mm total  length (25 mm once threaded into the valve).

Both work perfectly with our 40 mm or 70 mm Caffélatex Tubeless Valves.

Made in Italy.
