I happended to get a flat yesterday and this pump was so hard to use I could only get it to inflate to 30 PSI on my road bike tube. There is no place to leverage the push of your hand and the grip on the cyclinder is slippery. The best part is that there is a gauge but with all my hand strength I could not pump more than 20 times before the pressure from the tire made it impossible to put more air into it. I am returning this pump thanks to the great return policy at Sierra.
