Thanks to its smaller-diameter barrel, with Specialized's Air Tool HP Floor Pump it's easier than ever to inflate high-pressure tires. It also features Specialized's SwitchHitter head that works with Presta and Schrader valves, quality steel construction for excellent durability, and a three-sided base for superb stability. Plus, you'll love the comfortable, wide handle, easy-to-read oversize gauge and the nice, long hose.
