Crank Brothers

Sterling SG Pump

The ol' squeeze test works well enough when you're only a few miles from home, but what if you're pumping up a flat with hours left to ride? You best get the pressures nailed from the beginning and the built-in gauge in Crank Brothers' Sterling SG Pump lets you dial up tires all the way to 100PSI. The reversible head fits both Presta and Schrader valves, and the dual-action design has a high-volume setting for mountain tires, and a low-volume setting that puts more pressure into road rubbers. The whole shebang weighs just 141g, too, so it'll be an inconspicuous presence in your pack.
