Lezyne’s Gauge Drive HV is a compact high volume hand pump made of custom CNC machined aluminum for precise, lightweight construction. The high-volume design easily inflates mountain bike tires to the desired volume with fewer strokes. The overlapping handle and barrel, with oversized piston and shaft, are integrated into a compact design. It comes equipped with Lezyne’s ABS Pen Gauge, a compact in-line pressure gauge compatible with Presta and Schrader valves.
