The Lezyne Pressure Over Drive is an innovative floor pump with an integrated system designed to seat tubeless tyres. A secondary chamber can be manually pressurized and the stainless steel foot-lever releases the compressed air and discharges a strong, continued blast of air that quickly seats tubeless systems.
When using the Pressure Over Drive as a regular pump, air has to fill the chamber before it will start to fill an empty tyre/tube. This may take numerous strokes before the tyre/tube begins to inflate. When topping off a tube/tyre that already has pressure in it, the chamber will first have to reach the same pressure as the tyre/tube before it will begin to inflate it further.
