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.
