I had purchase a hand pump from [...] that was rated for a presta valve. The first time I used it, I could not inflate my tires, they got softer the more I tried. I immediately searched the internet for a substitute that would work with my compressor. Two days later I was back on the road.
This is a wonder of modern engineering - it actually enables you to fill a tire with a Presta valve using a Schrader style pump. Like squeezing apples and getting orange juice! Thanks EMS!
