Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

I use the Genuine Innovations Air Chuck. Compact and reliable.

I use he same one, very solid, though somtime it sticks open when using, think it’s from the co2 freezing the spring a bit and it won’t release.

I use the same.

I used to use ones that would work with unthreaded cartridges I could get at Walmart. It was mostly philosophical. I don't actually get enough flats to really concern myself with the price of a cartridge.

I am disappointed to learn that the Silca CO2 regulator is only 26 bucks. I was hoping for something with a bigger price tag more befitting of inflating MEILENSTEINS.

Hahaha...I know, right? It is a "very nice piece of kit," though; minimalist design, but threads on stem for secure fitment, has finger freezing protection, and regulates flow by simply pushing down. I've used a couple which operate clumsily, vaguely, and surprisingly but the Silca feels secure, predictable, and precise. I have no idea if it is the best (I've not used more than three or four over the years, and Silca is the second of my own, my first being a trigger operated unit, by GT I think, back in the early '90s), but it is very good.

I've found the PDW Shiny Object or Planet Bike Red Zeppelin work the best. I've had issues with the "push-to-release" style inflators like the Genuine Innovations or the Silca leaking as soon as the CO2 cartridge is opened. And the combo pump/CO2 inflator styles confirm the universal fit theory and are best left unpurchased.

In real life, I use this. You can use a threaded or non threaded 12 or 16 gram cartridge, and store one in the tool when not in use. Your hands won't freeze either.

I don't know why they bother to make these complicated. The Genuine Innovations one does the job. I have the Zeppelin as well, but pretty much never take it. I think it's hiding in a bag somewhere, but threading it on to the valve is more fiddling when you're trying to get that flat fixed.

The biggest thing is to match the size of the cartridge with your tire and desired pressure.

Inflation chart for different tire sizes and CO2 sizes - Mtbr.com

That eliminates the need for any valve or control even if it's a little more pressure than you would normally run. Thread the cartridge on, inflate, rock on.

None of us are in a race when it comes time to change a flat, but I have changed a flat in the dark while hearing a pack of coyotes not too far off. I'd rather get it done quickly.

EDIT: Oh yeah, remember to get a kit with the little foam sock for the cartridge. This helps with the freezing issue.

Double Edit: This is probably a more useful chart:

I really like the Lezyne Trigger Drive. Similar to the Genuine Innovations, but the spring is internal, and doesn't suffer from icing up. Also a bit longer and easier to hold onto. I have a PDW Shiny Object as well, but it's finish has not held up to being the in bag for a few years-- the markings on the control knob have completely worn off. I could never tell if the thing is in the ON or OFF position before screwing in the cartridge.

I have the Genuine Innovations version of that inflator for Mrs. rjones28's flat kit. Also, recommended.

I'll keep that in mind if I ever want to purchase a CO2 inflator I can pass on to my grandkids. Until then, the GI version gets my butt home.

If you need a foam sleeve buy a 3 pack of Planet Bike CO2 cartridges. The foam sleeve comes with the 3 pack.

I use very similar one. Get 12g unthreaded from Walmart like $7 for a dozen. They may not get you up to 110 PSI but certainly up to 80ish which is plenty to get you home.

This was probably just a fluke and I got my money's worth out of it, but with the plastic threads broken off the thing was unusable... couldn't screw the cart into the head. Genuine Innovations Ultraflate.

I've seen multiple instances of a rider using one of those non-threaded inflators (where the cartridge fits inside the case) fizzing out all the CO2 from assembling it badly. Riders using that style of inflator often say something like "I hope it works this time!"

Genuine Innovations Air Chuck

Another vote for the Air Chuck. I don't get very many flats, but it's worked very well each time. It's easy to control the inflation speed, even for a newby. And it's held the rest of the CO2 until the end of the ride, no leaks.

I use a sleeve made from an old inner tube section, wrapped with a rubber band. And that cushions the CO2 cartridge in my saddle bag, so it doesn't clank. I've never had the head freeze up, but I inflate at a pretty slow pace.

Lube the Air Chuck threads, to make it easier to thread on a cartridge, and feel when it's fully threaded on.

One time, I did blow out the o-ring that seals around the valve stem -- I was trying to put a tiny amount of pressure in the new tube before I mounted it on the wheel. I probably didn't push the inflator onto the stem far enough. Luckily, another rider also had CO2.

I've never seen this one. I do like the design, simple like the GI head, but able to dispense using index and middle finger to control the head. Huh--it threads onto the tube valve stem! So there's no need to press down onto the tube's valve stem to inflate.

Does it thread onto the valve cap threads, or the body threads? I have unthreaded tubes -- would it work with these?

Their youtube video (in German, but it's self explanatory. Or use CC auto translate--heh.)

I did the same thing once, because I forgot to open the valve on the tube.

For those who are new to C02 and reading this thread:

PLEASE do a "test run" on your C02 in your garage so you are familiar with how to use the device. Pro tip: hold the cartridge down (lower than valve). Please be comfortable with using this.

I can't tell you how often I am on a group ride and the person with a flat has C02 which he/she has never used, and they screw it up royally. It's not rocket science, but you may need to practice one or two times to be confident.

I don't like the push-to-inflate type. I prefer a knob to control the flow.

+1 on the Shiny Object. Simplicity personified. Get the kit with the leather sleeve though.

Red Zeppelin here. You can control the flow and if you don't need the entire cartridge you can easily close it off and save it. I have one for every bike and never a problem.
