- 【Perfect for Road/ Mountain Bike Tires】: 16 gram cartridge inflates a road tire to 100 psi and a MTB tire to approx. 40psi. NOTE: CO2 gas is ‘not’ food grade. As this cartridge dispenses its air, it rapidly cools and becomes COLD to the touch; care should be taken, protect your hands when dispensing air. IMPORTANT: For safety reasons - do NOT screw in and store a CO2 cartridge into an inflator head until needed for operation. Care & respect should be taken when using CO2 gas
- 【WARNING】: Never store the cartridges in or near any hot place, such as under direct sunshine, near a heat source or left in a car. Never use low quality CO2 head. Make sure the device has fully punctured the head of the cartridge. If not, or you find that the gas being released very slowly or the gas is freezing the head, discharge the gas for a few minutes until the bottle is fully empty, then dispose of properly.
The Ultimate Guide to CO2 Cycle Tyre Inflators
A CO2 inflator is a must-have tool for every cyclist. It helps you get back on the road in seconds when you have a flat tire. Unlike a hand pump, a CO2 inflator uses pressurized gas to fill your tire almost instantly. This guide will help you choose the right one for your bike.
Key Features to Look For
When shopping for an inflator, look for a “head” that fits your valve type. Most modern inflators work with both Presta and Schrader valves. You should also check if the device has a trigger or a twist-to-inflate mechanism. A trigger allows for better control, while a twist-to-inflate design is often smaller and lighter.
Important Materials
Most high-quality inflators are made from CNC-machined aluminum. Aluminum is lightweight, strong, and handles the freezing temperature of CO2 gas very well. Avoid cheap plastic inflators, as they can crack under the high pressure of the gas cartridge. Always look for a rubber sleeve or a grip, as the metal becomes extremely cold during use.
Factors That Improve or Reduce Quality
A good inflator offers a secure seal. If the seal is poor, the gas will leak out before it enters the tire. High-quality models feature a threaded connection to ensure the cartridge stays tight. Lower quality models might have loose threads or flimsy internal needles. These flaws often lead to wasted cartridges and frustration on the side of the road.
User Experience and Use Cases
CO2 inflators are perfect for road racers and mountain bikers who need speed. They are small enough to fit inside a jersey pocket or a tiny saddlebag. You should practice using your inflator at home before your first ride. This ensures you know exactly how to thread the cartridge and inflate the tire without any errors.
Frequently Asked Questions
Q: How many tires can one cartridge inflate?
A: Most 16g cartridges will fill one road bike tire or a portion of a mountain bike tire. Larger tires may need a 20g or 25g cartridge.
Q: Does the metal get cold?
A: Yes, the CO2 gas gets very cold when it expands. Always use a rubber sleeve or gloves to protect your hands.
Q: Can I reuse a CO2 cartridge?
A: No. Once you puncture the seal on the cartridge, all the gas will escape. You must use a fresh cartridge for every inflation.
Q: Will it damage my tire?
A: No, CO2 is safe for all standard bicycle tires. Just make sure to top off the tire with a regular pump once you get home.
Q: Is it better than a hand pump?
A: It is much faster than a hand pump. However, hand pumps are better for long-term use because they do not run out of gas.
Q: Do I need a specific size of cartridge?
A: Check your inflator’s manual. Some units only take threaded cartridges, while others accept non-threaded ones.
Q: Can I take CO2 cartridges on an airplane?
A: Most airlines forbid CO2 cartridges in carry-on or checked luggage. Check with your airline before you travel.
Q: How do I store the cartridges?
A: Keep them in a cool, dry place. Avoid leaving them in direct sunlight or inside a hot car for long periods.
Q: Should I carry a spare?
A: Always carry at least two cartridges. You might have a second flat tire or make a mistake while filling the first one.
Q: Is it easy to use for beginners?
A: Yes, it is very simple. Just screw the cartridge in, press the head onto the valve, and release the gas.
