Selected materials: The pump pipe is made of high quality aluminum alloy, which has a beautiful metallic shine. The smooth surface makes the pump elegant but also to ensure the durability of the product. With barometer: The barometer can show you the exact tire pressure, prevent overpumping, and indicate when pumping. Be more specific and more certain. WHY YOU NEED IT: The pedal can be bent 90 degrees, and the pump is small and delicate. If you need to drive or inflate, you can place this pump with just a little space. Easy to use: Simply remove the nozzle from the tire and place the pump in the nozzle to start pumping. Our pump has a lock that can lock firmly to the tire frame, so that it can be fixed to provide the tires with greater pumping comfort.
