Instead of messing with flimsy hand pumps with inaccurate gauges, pick up the Crank Brothers Sterling SG Hand Pump with Gauge for its premium machined aluminum body, easy-reading gauge, and ability to switch between high-pressure and high-volume airflow. Part of Crank Bro's Sterling series of dual-piston hand pumps, this particular version features a shorter stroke and gauge, lending the SG designation. One of the coolest features with the Sterling SG is the ability to switch between high-volume and high-pressure airflow, thanks to its air switch at the bottom of the pump. This means you'll be able to easily inflate both mountain and road bike tires--all without struggling just to get your tire pressure up to where you'd like it. High volume works for pressures from 0 to 40 psi, whereas the high pressure setting is best for road tire inflation from 40 to 100 psi. Another cool feature is the smart head, which automatically adjusts to both Presta and Schrader valves.
