Reviews over the

Trivio Valve extender

After removing the valve core from my Continental inner tube and fitting it in this extension, the valve does NOT work. The valve is no longer depressible and so no air can get in (or out). Ditto for the other valve extension and when using a different valve core. When fitting the extension to my original (and new) valve, the plastic tool already broke on 1st use.

Pros & Cons

Does not fit on my valves (vittoria corsa tubulars)
