25 Gram Threaded CO2 Cartridges

The JetBlack CO2 Cartridge 25g is a compact, high-volume threaded CO2 cartridge designed for fast trailside and roadside tyre inflation. With a larger 25 gram CO2 capacity, it is better suited to bigger-volume tyres than smaller 16g cartridges, making it a great choice for mountain bike, gravel and e-bike riders.

Compatible with most threaded CO2 inflators, this cartridge provides rapid inflation for both tubed and tubeless tyre setups. It is ideal for flat tyre repairs, race-day emergencies, or keeping in your saddle bag, hip pack or MTB tool roll as part of your on-bike repair kit.

The 25g size gives you more inflation volume when you need to get a larger tyre seated, rideable and back on the trail quickly. CO2 cartridges are single-use and are best treated as a fast emergency inflation option, with tyre pressure checked and topped up with regular air after the ride.
