Title: Works
Review: I bought this because I have a quality schrader pressure gauge but no way to get pressure off of my presta valve stems. My gauge works with the adapter on but my Blackburn pump does not. It will not depress the center of the valve stem far enough. It works fine on standard Schrader valve stems so there is something a little different going on with the adapter. I have to pump with the adapter off and put it on to take the pressure which gets old. The adapter does work alright with my compressor air hose attachment though I do have to press fairly hard. It makes filling tires at home easy but I will still use the thumb squeeze pressure gauge on the trail.
