If you need one great pump that can handle all your inflation needs, look no further than Avenir's AirSource 2X Shop Floor Pump. It's made with an all-steel barrel and features a wide, stable base. Plus, you'll appreciate the comfortable handle with contoured grip designed for one- or two-handed operation. It's quite tall, 23.5-inches in fact, and features 2 modes. The high volume mode fills big tires quickly and the high pressure mode gets up to 160psi. And the top-mounted gauge is easy to read while the universal head fits Presta and Schrader valves with no conversion.
