Innovative air pump with integrated system for tubeless tyres.
A secondary chamber can be pressurised manually and the stainless steel foot lever releases the compressed air. This discharges a strong, sustained blast of air, which quickly brings tubeless systems to a sitting position. Accurate analog display. Durable steel and aluminium construction with stylish wooden handle. Extra long, nylon reinforced fabric hose. Presta and Schrader valve compatible ABS1 Pro valve clamp.
If you want to use a Pressure Over Drive as a regular pump, there must first be air in the chamber before it can fill an empty tyre. This may take a few strokes before the tyre begins to fill. If it is only a matter of continuing to inflate a tube/tyre, the chamber must first have the same pressure as the tyre before it can release air and continue to inflate the tyre.
