Question
Valve core type
Just to be clear. Are these extenders suitable for valves with _non_ removable cores? i.e. I'd like to use them with the continental Giro Tubs...

answer 2
It already has a valve built in so you do not remove the existing core, just loosen the valve and screw this on.

answer 3
Yes, it suits non-removable cores well. you just need to mount it where you mount a valve cap, simple and easy. You can even do it after you you stick your tire to the rim..

Yes they will work. They are designed to fit on the end of the original valve. Leave the valve open as if you were inflating it and just thread onto the valve where the dust cap fits.

Yes you can use these with non-removable valve cores but pumping your tyre up requires access to the core so you can unscrew and tighten up the valve when required, so successfull pumping does depend on the amount of valve showing over the rim.

Question
CO2 friendly
There are some poor reviews on these. I just wonder if they work well with CO2 systems???

answer 1
Yes - I use the Innovate Microflate nano CO2 pump. No issues. You get a really good seal with these which is important as you only get one chance to get it right really. Much better than with the Zipp valve extender I used before and no messing about with tape.

Yes these can work with Co2 Canisters.
