Opening Dunlop (Woods) valve
#1
[attachment=5105]

I'm having trouble inflating the tire on my Dutch bike (I now live in the UK, no longer NL, by the way). It's got what I'm pretty sure is a spring-loaded or one-way Dunlop valve. As you can imagine since the valve is on my desk, the tube is now deflated.

The problem, I think, is that I can't get the valve to open. I'm using a reasonably potent two-cylinder pedal pump, but I can't seem to force air through the valve. When everything is seated properly to pump the tire, if I contort myself to hold the nozzle of the pump as tightly against the adaptor and valve as possible, the gauge on the pump gets up to around the 5 bar/70 psi mark, but the valve still doesn't seem to open, and no air is getting into the tube.

Any thoughts on how to solve this?

Scroll down for info and links to woods valve. Could be you need a replacement.

It might be time to convert to Presta valved tubes.

Just about. I decided the easiest solution was to get a new inner tube. As long as I was at it, I got one with a Schrader valve.

Yeh the schrader valve will fit without an adopter. Had no luck with presta. PITA.......YMMV.

In my experience, these clog up more than either schraeder or presta, but work very well otherwise. Usually you just need to replace the valve core.
