The cartridge set for airbags (CO2 + argon) from Scott consists of two replacement cartridges for the airbags in the Alpride range from Scott. One bottle is filled with CO2, the other with argon. The cartridges are easy to replace and also comply with the regulations of the International Air Transport Association (IATA). This means you can safely pack them in your luggage - even when traveling by plane. Safety has the highest priority here.
