The Air Tool Flex Pump features an inverted camber design. This design enables it to rapidly fill mountain bike tires. Moreover, it can also achieve the high pressures required for road bike tires.
Using this pump is easy. First, attach the pump head firmly to the tire valve. For mountain tires, you'll notice it fills up quickly thanks to the special design. When inflating road tires, just keep pumping until you reach the desired high - pressure. As for maintenance, keep it in a dry place and check the pump head regularly for any signs of wear. If the pump doesn't seem to be working well, make sure there's no blockage in the valve or the tube. Also, avoid dropping or hitting the pump as it could damage the internal parts.
