A digital high volume pump capable of seating tubless tires Innovative floor pump with an integrated system designed to seat tubeless tires A secondary chamber can be manually pressurized and the stainless steel foot-lever releases the compressed air. This discharges a strong, continued blast of air that quickly seats tubeless systems Equipped with super accurate, custom digital gauge Durable steel and aluminum construction with stylish wood handle Extra long, nylon-reinforced braided hose Presta and Schrader compatible ABS1 Pro chuck Max Pressure: 220psi / 15bar NOTE: When using the Pressure Over Drive as a regular pump, air has to fill the chamber before it will start to fill an empty tire/tube. This may take numerous strokes before the tire/tube begins to inflate. When topping off a tube/tire 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
