The Specialized Air Tool HP Floor Bike Pump is a high-pressure floor pump for filling bike tires. Requiring way less effort than a traditional floor pump, this will get your tires filled and you on the bike quickly. The SwitchHitter II head automatically switches between Schrader and Presta valves, taking the guesswork out of the situation and allowing you to help friends out with a little air, regardless of what type they use.
