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. It features an accurate ananlog gauge and a durable steel and aluminum construction with a stylish wood handle while the extra long, nylon-reinforced braided hose and Presta and Schrader compatible ABS1 Pro chuck make your life easier.
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.
