The Schrader valve located on the top cap of the AXEO is used to fill the cartridges with nitrogen. DO NOT tamper with the Schrader valve, as you run the risk of releasing the nitrogen charge from the cartridges, which will negatively affect the ride quality of the AXEOs. If the nitrogen charge is inadvertently released, the AXEOs will need to be sent into our facility in order to be re-charged with nitrogen.
