CXWXC CO2 Threaded Cartridges for Bike Tires, 25g 6 Pack, 3/8-24 Thread Rapid Inflation

CXWXC threaded CO2 cartridges deliver quick, portable inflation for bike tires, letting you restore ride pressure in seconds without a bulky pump.

If you ride road, gravel or mountain bikes, a compact CO2 cartridge is a practical backup when a flat threatens to end your session. CXWXC offers 16g and 25g threaded cartridges sized with a standard 3/8-24 thread so they fit most threaded inflators. The cartridges are single-use, lightweight and engineered to fill typical road or mountain tires quickly — ideal for roadside repairs, race support, and minimizing downtime on long rides.

How fast will a CXWXC 16g or 25g cartridge inflate my tire?

Both sizes release compressed CO2 almost instantly when punctured through a threaded inflator, delivering a rapid volume of gas to re-pressurize your tyre. The 16g cartridge is designed for most single-ride needs while the 25g gives extra volume for larger or lower-pressure tires.

• 16g: typically inflates a road tire up to about 100 psi or an MTB tire to ~40 psi in one shot.
• 25g: provides more gas for larger-volume tires or topping up after partial inflation.
• Instant inflation: gas is released quickly, restoring rideable pressure in seconds.
• Single-use: designed to be punctured and used once, then recycled appropriately.

Are CXWXC cartridges compatible with my inflator and valves?

CXWXC cartridges use the common 3/8-24 threaded fitting which matches most threaded CO2 inflator heads on the market. They can work with both Presta and Schrader valve setups when used with a suitable screw-on inflator head or valve adaptor.

• Thread size: 3/8-24 — widely compatible with threaded inflators.
• Valves: use an inflator head that adapts to Presta or Schrader as needed.
• Protect hands: dispenser and cartridge become very cold during release; use gloves or sleeve.
• Safety: never pre-install a cartridge in an inflator until ready to use.

What practical limits and safety points should I know?

CO2 behaves differently than atmospheric air: it cools rapidly as it expands and can leak out of tubeless or inner tube setups faster than regular air, so expect pressure loss over hours to days. Treat cartridges as single-use, recyclable items and follow handling precautions to avoid frostbite or pressure incidents.

• Cooling effect: cartridge and head get very cold while dispensing — wear gloves.
• Pressure retention: CO2 diffuses faster from tires; recheck before next ride.
• Storage: do not expose to heat or direct sunlight; avoid leaving in cars or near heaters.
• Disposal: cartridges are recyclable after fully discharging them safely.

Which size should I choose for my riding style?

Choose the 16g cartridge for lightweight, compact emergency inflation on road or typical trail rides where a quick top-up will get you home. Pick 25g when you ride wide tires, run lower pressures, or prefer extra gas for multiple top-offs between pump-ups.

• Road riders: 16g is often sufficient for a full road tyre inflation.
• Mountain or fat-tire riders: 25g gives more volume for larger casing sizes.
• Racing or group rides: carry extra cartridges if you expect multiple punctures.
• Combine with a mini-pump for longer-term pressure maintenance.

Who is this for? CXWXC threaded CO2 cartridges suit cyclists who want a compact, rapid inflation option for roadside repairs, racers needing quick pit stops, and commuting riders who value minimal weight and speed. They’re best used alongside a compatible threaded inflator and basic repair kit, ideal for riders who understand CO2 limits and safety precautions.
