This two-pack of 20-gram CO2 cartridges paired with a dedicated inflator represents the gold standard in portable bike inflation technology, designed by Crankbrothers—a brand synonymous with precision engineering and trail-tested durability. Whether you're tackling remote singletrack, bikepacking across varied terrain, or simply want backup inflation capability for road rides, this compact system delivers consistent, dependable performance when you need it most.

• 20-gram CO2 cartridges provide sufficient pressure to fully inflate most mountain bike and road bike tires from flat to rideable in seconds
• Threaded cartridge design ensures secure connection to inflator with zero gas waste or accidental discharge during handling

• Compact and ultraportable form factor fits easily into jersey pockets, seat bags, or frame packs without bulk or weight penalty
• Fast-action inflation mechanism delivers full tire pressure in under 30 seconds, minimizing roadside repair time

Real-world performance is where this system excels. Riders consistently report that these cartridges deliver the pressure needed to get a flat tire from completely deflated to trail-ready condition in under a minute. The threaded connection is intuitive—simply screw the cartridge into the inflator head, press firmly onto your valve, and you're inflating. Unlike some budget alternatives, there's no fiddling, no leaking, and no wasted gas. The dual-valve compatibility means you don't need to carry separate inflators for different bike types, making this solution genuinely universal. Whether you're on a gravel bike with Presta valves or a hardtail with Schrader valves, you're covered. Cold-weather riding is particularly where CO2 shines compared to manual pumps—your hands don't have to work the mechanism, and pressure delivery remains consistent even in freezing conditions.

This two-pack is ideal for serious trail riders, bikepacking adventurers, and anyone who wants genuine redundancy in their repair kit. If you're the type who values lightweight, reliable emergency gear and can't afford a repair failure derailing your ride, Crankbrothers' proven inflation solution belongs in your pack.
