AMZOON Bike Pump with Pressure Gauge Extended Hose Mini Bicycle Suitable for Schrader and Presta Valve Needle Inflating

[UNIQUE DOUBLE PISTON CONSTRUCTION] With a double piston construction, this bike pump has two pumping techniques to ensure that it continues to inflate quickly under extremely high pressure. In volume mode, both pistons can move, increasing the inflation speed by 35%. If the resistance is too high, setting the bicycle pump in high pressure mode can reduce the energy by 35%. It continues to inflate rapidly under high pressure. [EXTENSION TUBE + PRECISE MANOMETER] The pump has a long, flexible hose that can be used in any position, no matter how comfortable it is. The tires are effectively inflated at a high pressure of up to 120 PSI / 8 bar. Unlike a mini bike pump without a pressure gauge, you can see the tire pressure from the data displayed on the pressure gauge to inflate your tyres accurately. [Easy to carry] Our portable bicycle pump is 27.5 cm long and weighs only 165 g. It is made from strong aluminum alloy and durable hard plastic. Inflator bicycle length and weight account for only two-thirds of comparable products, which is quite compact. Bike pump also be attached to cycling equipment and backpacks, making it particularly suitable for professional cyclists. [COMPATTIBILITY] As our hand pump is equipped with 3 valve configurations, our single head hose allows quick change of Presta and Schrader and Dunlop valves. Likewise, the secure valve connection with metal thread ensures optimal sealing. Bicycle accessory lasts twice as long as conventional valves. [COMPLETE ACCESSORIES, MULTIPLE BENEFITS] 1 mini pump + 1 adapter + 1 air nozzle + 1 ball needle + 1 mounting bracket + 1 grinding tablets + 2 screws + 4 thread patches. At the same time, it has several advantages: "Double piston system", "Hose extension", "Precise pressure gauge", "Light and easy to use. transport", "Chang" Easy between 3 types of valves".
