Jar of 50 Velox threaded CO2 cartridges

The CO2 refill cartridge is the ideal ally for re-inflating your inner tube or tubular. Designed for easy re-inflation, this accessory is equally at home on a road bike, mountain bike, city bike or ebike. The CO2 refill cartridge contains air adapted to the pressure required by all bicycle tires. Tubeless tires are re-inflated to 2.5/3.0 bar for mountain bikes and 7/9 bar for road bikes, depending on tube diameter. A CO2 refill cartridge is used only once. To avoid the impact of cooling on the hands, it is recommended to hold the cartridge by the protective label or with a glove when using it.
