The Lezyne Digital Pressure Overdrive features a unique chambered design, making it perfect for seating even the most stubborn tubeless tires. The secondary chamber can be pumped to pressure, and a stainless - steel foot - lever releases compressed air in an immediate, continuous discharge, quickly and easily seating the tire bead. It has a durable steel and aluminum construction paired with a digital gauge for ultimate accuracy and precision. An extra - long, nylon - reinforced braided hose with our Presta and Schrader compatible ABS - 1 Pro chuck offers great versatility. Note: When using it as a regular pump, fill the air chamber first before air flows into an empty tire/tube. When topping off a pre - pressurized tire/tube, the chamber must reach the same pressure as the tire/tube before further inflation.

Using the Lezyne Digital Pressure Overdrive is easy. For seating tubeless tires, pump up the secondary chamber to the desired pressure. Then, use the stainless - steel foot - lever to release the compressed air quickly and seat the tire bead. When using it as a regular pump, make sure to fill the air chamber first if the tire or tube is empty. If the tire/tube already has pressure, the chamber needs to reach the same pressure before it can add more air. As for maintenance, keep it clean and dry. Check the digital gauge periodically for accuracy. If you notice any damage to the steel barrel, piston, or the hose, get it repaired or replaced promptly.
