Pressure Drive Pump

The Lezyne Pressure Drive Pump has all the functionality of Lezyne's Carbon Pressure Drive, just fabricated out of CNC-machined aluminum. You get a nice price break for a minimal weight penalty. The Small pump is 170mm long, while the Medium is 216mm long.

Pressure Drive pumps are High Pressure units, HP for short, designed to pump up road tires. What separates Pressure Drive pumps from Road Drive pumps are the barrel diameters. 20mm vs. 17mm. You can push more air with a larger diameter barrel and thus pump a tire up faster, but it will take more arm strength to do so.

One of the great features of Lezyne mini-pumps is that they all come with flexible thread-on hoses rather than a fixed pump head. This is a huge benefit for a few reasons. One is security: thread it on to a Presta or Schrader valve and it won't come off. Another is ergonomics; you aren't limited by holding the pump at a perfect right angle to the valve. A third is that this Flex Hose is ABS-equipped -- it has a bleeder valve on it.

The Lezyne Pressure Drive Pump comes in two lengths: Small and Medium. Maximum pressure that one can attain with this pump is 120psi. There's even an accessory Pen gauge hose that screws into Medium pumps. The pump comes in High-Polish Black.
