The Jetblack CO2 Cartridge 16g is a compact, single-use gas cartridge designed to quickly inflate bicycle tyres. Compatible with most threaded inflators, it delivers rapid inflation for tubed or tubeless setups, making it ideal for roadside fixes, races, or quick top-ups. Note that CO2 cartridges are best used as a fast temporary fix, with tires topped up by regular air afterwards and replaced when needed due to single-use nature and potential temperature effects on rubber.
