PRO BIKE TOOL CO2 Cartridges - Threaded CO2 Canisters for Bike Tires - Quick Inflation for Road, MTB, Cyclocross, Gravel, Hybrid Bikes - Portable, Durable, Essential for On-The-Go Repairs

I’ve been using this brand for several years now and have never had a bad experience with these cartridges. Always worked when needed. I will continue to use these in my saddle bag so when a flat happens I have a reliable cartridge with me to get me back going. I use these on my bike with 700C Road tires. Have used with both 25 and 28 width Road tires.

These CO2 cartridges are a great item to have as part of your bike repair kit. The cartridges along with the tire valve connector tool makes for a compact tire inflation system to have for that occasional time you need to change out a flat. Just be aware of the water vapor in the ambient air freezing on the tool as you release the CO2 to inflate the tire / inner tube.

Unfortunately, I get a lot of flat tires where I ride. These cartridges screw in easily to my inflator and easily fill my road bike tires to a high enough PSI to get me through the rest of the ride when I flat. Given the large quantity, it was an economical buy.

Use it when I have a bike flat on a ride. Works perfect.

Muy buenos

Husband started racing bikes this year. He loves these for convenience for flats that happen often in this high desert of Southern New Mexico where there are a lot of goat-head stickers that are RUTHLESSLY effective stabbing anything. He likes being able to quickly fix the flat and be back racing. Pretty proud of him, being he placed second in a 26 mile mountain race at aged 52! Winner was no more than 30. Happy to help support those endeavors with these. Nice value in multi pack.

Perfect set up and size.
