At only 7" long this is almost into the "micro" pump category, but we'll let it slide. The Blackburn Airstik 2-Stage mini pump easily fits into a jersey pocket and inflates a 700x23 tire up to about 110 PSI. It also has this cool two-stage system that lets you flip a switch for low-pressure pumping when you're just getting started, then switch to high-pressure, low-volume pumping to finish it off. Pretty good for a little guy like this. But don't be fooled by the small stature. This little guy is built tough for all day riding and abuse.
