By far, the best Presta valve extender available. Unlike other extenders, this one allows you to screw and unscrew the valve in to put in air, or to release air. Whereas other valve extenders require you to remove the tube's valve core, or leave the valve core unscrewed in order to air up the tire (which comes with its own issues), the Topeak valve extender doesn't require this. This is important for TPU tube users because 95% of TPU tubes currently do not allow for complete valve stem removal without ruining the tube. The Topeak valve extender is the absolute best thing for this if you're running deep carbon fiber rims because the extender fits into the rim and onto the tube with relative ease where it creates a perfect seal (without Teflon tape!) between the valve extender and the tube's valve stem giving you easy and useful access for airing up your tires. I've already purchased two of these and I wouldn't hesitate to purchase them again. Highly recommended, don't think twice about getting them for yourself! Five stars all day long.

Really cool design, threads directly onto a presta valve without removing the core. Can even lock and unlock the valve top nut with the extension at the top. However they are nominally larger in diameter than a presta valve stem, and if your wheels have tighter tolerances on the valve holes, they may not fit through.

Worked as it should.

Very nicely made. I was skeptical but it is quite clever and works really well. Just to be clear, this is not like the semi-permanent presta valve extenders where you move the presta valve working guts to the end of the semi- permanently attached new extension tube. This Topeak device screws on for the pump up and then you take it off and tighten the valve per normal (ie. you need to have enough of the presta valve poking through the rim to be able to release the valve for the Topeak screw-on piece.) If your valve stem is so short as to be hidden down in the rim - get the semi-permanent extension tube referenced above (Continental makes some good ones, also at a ridiculously high price.I like the Topeak "temporary" extender enough that I even bought a second one, despite the ridiculously high price - the only downside in my view.

Endlich eine Ventilverlängerung die auch mit Minipumpen zu benutzen ist. Die Technik ist zuerst etwas knifflig, wenn man den Dreh heraus hat, funktioniert es super.
