Lezyne Pressure Over Drive black

A secondary chamber can be manually pressurized and the stainless steel foot lever releases the compressed air. This releases a strong, continuous flow of air that quickly raises tubeless systems. Equipped with a high-precision, custom digital pressure gauge. Durable steel and aluminum construction with elegant wooden handle. Extra long nylon reinforced braided hose. Presta and Schrader compatible ABS1 Pro chuck.

When using the Pressure Over Drive as a regular pump, the chamber must fill with air before an empty tire/tube can be inflated. This may require several strokes before the tire/tube begins to inflate. When refilling a tire/tube that already has pressure, the chamber must first reach the same pressure that the tire/tube has before it can be inflated further.
