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

Perfect set up and size.

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.

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.

Package arrived on-time, as described. 20gr. CO2 cartridges were protected well for shipment. Have not used them, yet.

Have not used them long but seem to work OK.

Came as advertised and was good price.

As promised

Very good product
