I have a Motobecane with Specialized 27 x 1¼ tires in my scrap heap. I don't know what kind of tube is in there but I've never seen a valve like that before on a car, truck, tractor or bicycle wheel. It's a tiny little thing and I couldn't succeed in getting any air in there at all. Are these still around? Is some adaptor required? I tried air from the compressor and from two different hand pumps but they all seemed to only spray a little wind around the top, without injecting any. I suppose if the wheels are good, I could drill or file a proper sized hole for the typical valve stem.

What's the story?
