Crank Brothers Power Pump

Air is free! All you need is a device that makes all that free air work for you. Crank Brothers' Power Pump does the job, and weighing only 93 grams you'll hardly even notice it's along for the ride. It's also less than 6 inches long so you can easily carry it in a pocket or pack. And, you'll love being able to switch inflation settings to maximize pumping power for high-pressure (road) and high-volume (off-road) tires. The Power Pump's dual head fits Schrader and Presta valves, too.
