Lezyne HV Drive Pump

A high volume pump is designed to move a large amount of air with each stroke, making it ideal for mountain bike tires or wider gravel tires. It is less efficient for high-pressure road tires, which require a high-pressure pump to reach the necessary PSI.

The size difference primarily affects the length of the pump and the volume of air moved per stroke. The Small version is more compact and easier to stow in a jersey pocket or saddlebag, while the Medium version is slightly longer, allowing you to inflate your tires with fewer strokes.

Lezyne pumps typically utilize a reversible hose or head system to accommodate both valve types. You will need to unscrew the hose and flip the internal fitting to switch between Presta and Schrader compatibility.

Yes, the Lezyne HV Drive includes a composite matrix frame mount that attaches to your bike's water bottle cage bosses, allowing you to carry the pump securely on your frame.
