Lezyne Pressure Over Drive Pump For Tubeless – Black

Featuring a unique chambered design, the Pressure Over Drive Air Pump is ideal for seating even the most stubborn tubeless tires. The secondary chamber can be pumped up to pressure enabling a stainless steel foot-lever to release the compressed air in an immediate, continuous discharge, quickly and easily seating the tire bead.

The features a durable steel and aluminum construction paired with a highly accurate and precise analog pressure gauge. An extra long, nylon-reinforced braided hose terminates in our Presta and Schrader compatible ABS-1 Pro chuck offers plenty of versatility.

 

: Innovative chuck quickly and securely seals to Presta or Schrader valves. Air Bleed System (ABS) button for easy pressure tuning. Quick release design allows for instant disengagement from Presta valve. The 90-degree bend is for ergonomics and simplicity and compatible with aero disc wheels. Equipped with a clever aluminum/brass construction and an integrated valve core remover, the ABS-1 PRO Chuck is also compatible with flip chuck valves.

When using the Pressure Over Drive as a regular pump, you must fill the air chamber before air will begin to flow into empty tire/tube. When topping off a tire/tube that already has pressure in it, the chamber will have to reach the same pressure the tire/tube is at first before it will begin to inflate it further.
