60mm removable alloy valve extension to inflate all Mavic road wheel-tyre systems. Thanks to a specific machining, the top end of the extension enables to open (and close) the valve before using it to plug the pump.
Features: • Weight: 5 (60mm) grams • Compatible with all Mavic road wheel-tyre systems • Easy to use open and close valve

I own some cosmics and the brass valve extenders are cheap, ugly and nasty. These enable you to firstyl open the valve by twisting with one end, secondly remove then use the other end to attach to the tube and inflate. Thirdly remove and use the first end to close the valve. You can now inflate your tubes even if the valve is under the deep rim without the need of valve extenders. No valve extenders are exposed when riding. You only have to purchase one to inflate both tyres.
