Reviews over the

Trivio Valve extender

The Schwalbe variety turned out to be out of the range, so then these. Bonus is that they are black, but otherwise I cannot recommend them. They are not airtight, which can be solved with Teflon tape, but also the fit of the supplied tool is not very good, which is not useful when you have more resistance in the thread because of the tape. Fortunately, I still had the little tool from Schwalbe lying around and now it is airtight. Hassle and will be especially so if you have a leak on the road and have to transfer the valve extenders. Fortunately I still had one set of schwalbe left, so I just put those in the saddlebag. I don't buy them anymore.
