Standard road-size CO₂ cartridges often do not carry enough volume to properly inflate a mountain bike tire. These larger 25-gram versions provide the extra gas needed to bring a high-volume MTB tire up to usable pressure in one shot. Paired with a compact inflator like the AirChuck, they make it possible to quickly inflate a tube or bring a repaired tubeless tire back to pressure so a rider can get moving again.
