Fast and safe inflation for adult and children’s bike tyres. Inflates a bike tyre in seconds with no effort. Check our tyre pressure inflator chart below to ensure correct inflation pressure for all different types of tyres. Detailed instructions written in English included. Use with 16g ICO brand CO2 threaded cartridges. Cartridges are not included with the inflator. To operate, ensure the inflator handle is set to the closed position “C”; insert an ICO brand 16g CO2 cartridge into the included rubber foam sleeve; gently screw on a 16g CO2 cartridge; connect your inflator head to your tyre; and open the valve to the “O” position. Do not store the inflator with full cartridges attached. Leak Proof connection compatible with Presta and Schrader valve tyres. Do not use with valve extenders. For Presta valves with removable valve cores, tightly screw the core into the valve stem to prevent the core from falling out. We recommend testing this maneuver at home before using on a long ride. Cartridge and inflator will get cold when expelling gas. The included rubber foam sleeve goes around the cartridge while inflating your tyre to protect your hands from the cold. The inflator sleeve can be reused after the charger is empty.
