Lezyne | Pressure Over Drive

Blast stubborn tubeless beads into place with controlled, high-volume air.

The Lezyne Pressure Over Drive is a high-volume floor pump designed to make seating difficult tubeless tires easier. Its chambered design stores compressed air before releasing it through a stainless steel foot lever in an immediate, continuous discharge to help quickly seat the tire bead.

Built with durable steel and aluminum components, the Pressure Over Drive features a precise analog pressure gauge and an extra-long, nylon-reinforced braided hose. The ABS-1 Pro Tubeless chuck supports both Presta and M6x0.8 valves, adding versatility for different setups.

Important Compatibility Note

When used as a regular pump, the air chamber must be filled before air begins flowing into an empty tire or tube. When topping off a tire or tube that already has pressure, the chamber must first reach the same pressure as the tire or tube before additional inflation begins.
