Inflating tires with tiny hand pumps is tedious work best reserved for trailside emergencies. Floor pumps, on the other hand, offer bigger air potential, in faster and mores table applications, and the Crank Brothers Gem Floor Pump is one to achieve just that -- big pressure in short amounts of time. It uses a large chamber to send out massive volumes of air into your tire in quick pumps, and has a foot-activated switch for switching things up when you need to run high-pressure instead. When the switch is activated, the pump uses a smaller air chamber, offering shorter bursts of air, but capable of achieving pressures as high as 160-PSI, for quick-rolling road riding. The Gem comes to you ready to run both Presta and Schrader valves, and has a hidden needle and plastic valve adapter for the days when you need to pump up other sporting goods from your garage.
