Caffélatex Valve Extensions are tubeless-specific, but they work just as well on any removable-core Presta valve fitted to a deep rim. Tight tolerances give a reliable, leak-free seal.

Highlights

  • Pack of two
  • Externally threaded, so the valve can still be secured to the rim
  • Fits any removable-core (RVC) Presta valve
  • Nickel-plated brass body made to tight tolerances
  • Stable and quiet in tubeless and tubed set-ups
  • Pairs with Caffélatex Tubeless Valves

Built for tubeless

The external thread lets you secure the valve to the rim and keep the tubeless seal air-tight, and it keeps the extension stable and rattle-free on tubed wheels too.

Compatibility & fit

Works with any Presta valve that has a removable core, including Caffélatex Tubeless Valves. The 35mm extension adds 25mm once threaded in; the 45mm adds 35mm. Fitting and set-up are a separate Tune Cycles workshop service and are not included.
