Just as the name would imply, the engineers at Lezyne intended for the Pressure Drive to be a high pressure pump. While it is an impressive feat to juice 120psi out of a mini pump, we're simply amazed the Pressure Drive can achieve this in such a small 89 gram package. Chapeau Lezyne.
The two piece, all CNC alloy design has an overlapping handle and barrel that fit together with surgical precision. These tight tolerances help explain how the pump gets up to 120psi. Like other Lezyne pumps, the Pressure Drive the ABS Flex Hose. It highlights include a dual head for servicing both Presta and Schrader valves and the ABS valve release. This is an Air Bleed System which is a small pressure release button on the pump head. Possibly the finest mini pump for a road bike ever made.
