Crank Brothers Sterling SG Pump

Crank Brothers' Sterling SG Pump features a tough aluminum barrel a little shy of 8 inches long for maximum pumping power; a switch to select high-volume (off-road tires) or high-pressure (road tires) inflation, and a handy built-in gauge. The universal head gets up to 100psi on either Schrader or Presta valves without having to switch the head.
