ICO (10-pk) 16g Threaded CO2 Cartridges
Best for fast, reliable tire inflation on the road or trail. These 16g cartridges are designed for high-pressure inflators and can bring a standard road tire to about 100 PSI quickly, or an MTB tire to roughly 40 PSI. They’re compatible with standard 3/8″-24 threaded inflators and are described as food-grade purity CO2, minimizing metallic aftertaste in beverages when used elsewhere. Choose this if you want dependable performance from a widely compatible package and occasional non-tire uses.
Best for: road cyclists and mountain bikers who value instant inflation and universal 3/8″-24 threading. Might be less ideal for inflators with special heads or those who prefer larger 25g cartridges for fewer changes on long rides.
Caution: CO2 can displace air pressure quickly in tires, so plan to top off with a proper pump if tires lose pressure over time.
CXWXC 16g/25g Threaded CO2 Cartridges (12 Pack)
Best for riders who want flexibility in cartridge size and reliable, fast fills. The set includes 16g and 25g cartridges with 3/8-24 threads, compatible with most threaded CO2 inflators. This option is ideal for riders who prefer a compact package that can handle varying tire pressures. It’s noted to be lightweight and easy to carry, perfect for saddle bags or jersey pockets on long rides.
Best for: trail and road cyclists who value compact form and quick inflation. Better for shorter trips or emergency resets rather than prolonged use without re-inflation. Note: CO2 escapes faster than air, so re-inflate with air after a ride if needed.
Caution: The effect of CO2 is temporary; keep in mind you may need a follow-up pump or reinflation after a short period of time.
Gorilla Force 16g CO2 Cartridges (5 Pack)
Best for riders who want a balanced, shop-quality cartridge in a compact pack. The Gorilla Force cartridges feature universal compatibility with standard 3/8-24 threads and a flat sealing surface for consistent CO2 volume. They’re designed for quick roadside inflation, making them suitable for road, MTB, gravel, and even e-bike applications where a fast top-off matters.
Best for: riders who want shop-grade quality in a portable multi-pack. Choose this if you value reliable seals and consistent CO2 output. Limitation: some inflators with integrated cartridge storage may not fit 16g cartridges in certain designs.
BriskMore 16g Threaded CO2 Cartridges (12 Pack)
Best for casual riders who want an economical, ready-to-use solution. Each 16g cartridge delivers about 100 psi to a road tire and around 40 psi to a mountain tire. The BriskMore set comes with an insulated sleeve and emphasizes recyclability, pure CO2, and compatibility with threaded inflators. It’s a solid choice for beginners or riders who prefer bulk purchases for events or teams.
Best for: daily riders seeking affordability and reliability. Avoid this if your inflator head requires a different cartridge diameter or if you need refillable cartridges for long-term use (these are one-time-use and not for refilling).
Genuine Innovations G2153 16g Cartridges (Pack of 6)
Best for brand-conscious buyers who want guaranteed compatibility. These 16g cartridges are explicitly described as compatible with Genuine Innovations inflators, with pure CO2 and no additives or oils. They’re tailored for road and standard bike tires, offering straightforward usage and reliable performance with compatible inflator heads.
Best for: riders who already own Genuine Innovations inflators or value pure CO2 without additives. Limitation: not all inflators are guaranteed to work with non-Genuine Innovations heads, so verify compatibility before pairing with a third-party inflator.
Buying Guide
What size cartridge should you choose?
16g cartridges are the standard go-to for quick inflation on most road and mountain bikes. Some sets include 25g variants for longer rides or fewer cartridge changes. If you ride frequently and tend to run close to flat, a mixed-pack can minimize downtime.
Do you need universal threading?
Most inflators use 3/8-24 threads. Confirm that your inflator head and mounts are compatible with this threading to ensure a tight seal and reliable CO2 delivery.
Is packaging matter or perceived quality important?
Higher-pack-quality cartridges with better sealing surfaces reduce the risk of leaks. Premium brands often advertise consistent CO2 volume and fewer jams, which improves reliability in urgent situations.
What about environmental considerations?
CO2 cartridges are typically single-use and recyclable in many areas. Look for recyclable packaging or sleeves that help protect your hands during inflation, and consider composting or recycling programs where available after use.
Should you worry about additives?
Some cartridges claim pure CO2 with no additives. If you have inflator heads sensitive to additives or oils, choosing cartridges that explicitly advertise pure CO2 can prevent residue buildup in valves and heads.
Portability and practical use
Compact 16g cartridges fit easily into saddle bags or jersey pockets. If you expect longer rides, consider a 12-pack or 15-pack for quick access, avoiding frequent replacements on the trail.
FAQ
- Are CO2 cartridges safe for all bike tires? CO2 is generally safe for standard road and MTB tires but can cause a temporary loss of pressure in tubeless setups; reinflation with air may be necessary.
- Will CO2 cartridges freeze the inflator head? Yes, releasing CO2 can cause the inflator head to become cold; wear gloves if needed.
- Can I reuse CO2 cartridges? No. They are designed for single use and should be recycled where possible.
- Which brand offers the best compatibility? Look for 3/8-24 thread cartridges that match your inflator head. Some brands emphasize cross-brand compatibility, while others pair best with their own inflators.
- Is pure CO2 better than gas with additives? Pure CO2 reduces risk of clogging inflator heads and valves, providing smoother operation.
