Ideal for riders, racers and commuters who want a lightweight, quick roadside inflation backup for puncture repairs.
These 16 g threaded CO₂ cartridges are a compact emergency inflation solution for getting your tyre back up to pressure quickly. With six cartridges in the pack, you have spares for multiple rides, training sessions or race-day repairs without carrying a conventional pump.
Each cartridge uses a 3/8''–24 UNF threaded connection, so it is suitable for use with compatible threaded CO₂ inflators. The gas delivers rapid inflation in seconds, which is particularly useful when you want to minimise time spent stopped beside the road or trail.
The steel construction is recyclable after use. CO₂ cartridges are single-use, so we recommend carrying a backup cartridge and checking that the tyre is correctly seated before inflation. The cartridge can become very cold during discharge; use the inflator’s protective sleeve or avoid holding the bare cartridge while releasing the gas. Store away from heat, as it contains gas under pressure.
