Equipped with the 2Stage 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 2 bar / 30 psi is achieved with 30 per cent less power compared to a normal floor pump. Stage 2 uses only the small cylinder to achieve high pressures up to 11 bar / 160 psi. The TwinHead™ DX5 pump head with long hose makes it easy to reach valves. For maximum stability and durability, the base and cylinder are made of robust steel. Compatible with Presta and Schrader valves. - Head: TwinHead™ DX5 with long hose - Weight: 2.5 g - Details: - Volume: 715cm³ (Stage 1), 258cm³ (Stage 2) - Pressure gauge: 0-30 psi (Stage 1), 30-160psi (Stage2) - 360° rotatable hose - Ball needle / air mattress adapter - Hose lock - Maximum pressure: 11 Bar - Type: Stand pump - Pressure gauge Material - Cylinder: steel - Handle: rubber - Foot: hardened steel Dimension - Height (mm): 74 mm - Length: 26.6 mm pump - Compatible valve types: Car valve (AV).
