The JoeBlow Sport pump features a unique 2-stage design that allows you to inflate at both low and high pressures in record time. The first stage has both cylinders open and quickly reaches 2 bar with 30% less effort than a standard floor pump. The second phase then uses a small cylinder to achieve pressures up to 11 bar. The TwinHead™ DX5 extra-long hose head with hinge makes it easy to access the valves. The durable steel body and large steel base give the pump great stability. head: TwinHead™ DX5, for Auto / Galusky / Dunlop Valve Body: Steel / Anodized Aluminum Manometer: 160 psi / 11 bar, 3", Stage 1: 0-30 psi, Stage 2 30-160 psi Hose: X-Long 360 Pivot Pressure: 160 psi / 11 bar Base: Hardened Steel Dimensions: 74 x 26.6 x 18 cm Weight: 2.5 kg Art.No.: TJB-S2STG
