Gorilla Force CO2 Cartridges for Bikes - Threaded 16g & 25g Refills for Tire Inflators, Bicycle Cycling, Road MTB Gravel E-Bike, Fits Most C02 Inflator Heads, Fast Flat Repair for Tubes & Tubeless

Perfect for my purposes, price seems reasonable.

Works great to have on hand to fill a flat tire on my road bike. It’s easy to use and inflates the tire after I plug it. I can continue to ride on the tire and make it home on a long ride.

Do what they’re suppose to do. Reasonable price.

Every single one worked flawlessly—no leaks, no duds, just solid performance. But man, I wish they were a bit more budget-friendly. My wallet cries a little every time I stock up

These are a must if you ride longer routes. If you have a flat tire and a spare TPU tube, to save space, in your under seat bag, with the proper head you can get a 29” tire usable with one cartridge and a 2nd will get you in real good shape.

I got these as supplemental canisters for long motorcycle trips. They're bigger than standard canisters so hold more air. Just what I needed.

It works. The threads screw in nicely. The containers seemed consistent in fill. Much cheaper for a box than buying it one by one at the bike shop. Plus the ones at the bike shop had malformed threads, so this is better quality AND LESS expensive. You use the CO2 and then once the tires are seated, you empty and put in regular air.

Not much to say. They work. They’ve saved my butt many times on long bike rides.
