The Lezyne Digital Pressure Overdrive Floor Pump is designed for efficient tubeless tire seating with a unique chamber system. A secondary chamber can be pre-pressurized and released instantly via a stainless steel foot lever, providing a continuous burst of air to quickly seat even stubborn tire beads. Built with a durable steel and aluminum, it features an extra-long, nylon-reinforced braided hose and an ABS-1 Pro Tubeless Chuck compatible with Presta and M6x0.8 valves. A highly accurate digital gauge ensures precise inflation, making it a reliable tool for both tubeless setups and standard inflation. When used as a regular pump, the air chamber must be pressurized before filling an empty tire. It also must match the existing tire pressure before adding more air. The Lezyne Digital Pressure Overdrive Floor Pump is an ideal choice for tubeless tire users.
