Is the air in your tires gone? It'll be back when you've got Axiom's Terminateair MV Hand Pump. Its CNC machined from lightweight aluminum for strength and has machined grooves and textured surfaces for added grip. The durable aluminum pump shaft and medium-volume barrel is ideal for both high-pressure road tires and high-volume MTB rubber. An extendable hose takes stress off valve stems, and the Re-Valver connection easily switches between Schrader and Presta valves by simply twisting the valve barrel.
