Equipped with 2-stage technology, the JoeBlow ™ Sport 2Stage achieves large volume and high air pressure in record time. Stage 1 uses both cylinders for a large volume, so that 2 bar / 30 psi can be achieved with 30 percent less force compared to a normal floor pump. Stage 2 uses only the small cylinder to reach high pressures up to 11 bar / 160 psi. The TwinHead ™ DX5 pump head with long hose makes valve accessibility particularly easy. For maximum stability and durability, the base and the cylinder are made of robust steel. Compatible with Presta and Schrader valves.
