AirCap / Bicycle Accessories


AirCap is a lid set on the valves inside the tube and is used to inspect tube pressure. After screwing the AirCap on valve inside, the air box in it will be integrated with the inner tube of bicycle. When tube pressure falls below a certain limit, AirCap’s internal mechanical structure will be driven into work by the changes of its air pressure inside. In this way, red small airbags will pop out on both sides of it to inform the tube pressure condition to the rider. When the tube pressure is sufficient, airbags will retract without any influences on riding. AirCap adopts a pure mechanical structure, which is convenient and efficient.
