Genuine Innovations G2673, AirChuck, Lightweight, Bicycle CO2 Inflator, weight 16g, Black

My family and I took our dirt bikes up to the mountains of NM. We rode all over the place for three days. On our last day I got a flat on the rear wheel of my bike. I had one of these I with me and I used the 16gram and had plenty enough air to have got me back to the truck. Turns out the hole in the tube must have been pretty sever I ended up using both cartridges trying to get myself back to a road where we could come get the bike with a pickup. Was very impressed with it! It seems to be well made it's a great back up in a case such as this! I liked the fact that it shuts the air flow off so that it doesn't waste what you didn't have to use! Especially in the part of the world I was in! Every bit of the excess was crucial to get the bike off the trail. It's very easy to use. Do put something around it when you discharge it because it gets really cold really quick. Over all I would and have recommended this to everyone that goes off road to the middle of nowhere. It will sure help you get closer to cilvilization and at least you won't have to walk as far! I didn't have a tire gauge with me when I used it I just kind of ran it by feel but it was real close to what I usually run in the tires just by the way it felt. Great pocket tool it's small enough to be easy to take with you anywhere I'd recommend carrying extra cartridges just in case you might need them. I only had the two that it came with and had I been farther out from a road I would have needed more to get back to a road. Thankfully I wasn't too far from the road

I bought this inflator about a month ago and yesterday I got my first flat since deciding to carry this Elite Inflator instead of my hand pump. I've had to change/repair MANY flats in the last 3 months and trying to pump a 700c x 23 to 110-130 psi can be exhausting with a small hand pump. Anyway, I went on a short ride to the Metro rail and while riding the train, I noticed my front tire was flat (I checked the tire pressures before I left home @ 120psi). I recently purchased this vintage Nishiki Tri-A and the tires and tubes looked to be over 10 years old. When I dismounted the tire, the old rubber rim strip had split, which I was expecting as I had replaced the rear rim strip awhile back so I carried a new rim strip, new tube, tire levers and my CO2 Inflator w/2 16 gram cylinders. Was in a hurry, so I didn't want to bother with a patch as I didn't have any water nearby and didn't want to use the Inflator to test for the leak, so that is a con for the Inflator. Installed the new strip, installed the new tube and remounted the tire and hit it with the CO2 Inflator. Awesomeness! In 10 seconds, my tire was filled... I didn't use up quite all the gas, but I should have... When I got home, I checked the tire pressure and it was at 110psi, so if I had used every bit of the gas, maybe it would have hit 115psi, certainly within the pressure range of my tires.With my old hand pump, to go from 100 psi to 110 psi takes about 100 pumps and I've often needed a few minutes of rest after pumping up a tire... This inflator works great, it is so much faster and is so convenient and easy to use. I bought a box of 25 cartridges for about $30 which is way less than the bike shops, so it costs me a bit over a buck to fill a new tube with this inflator. For the ease of use it is well worth it in my book! Of course they are so much smaller than a pump as well but I don't know about weight savings as I'm now going to start carrying 3 cylinders with me.I used mine on a Presta valve, but looking at the mouth of the Elite Inflator, it should certainly work with Schrader valves as well. I always carry a daypack so I always bring my tool kit and tire kit, but my little behind the saddle bag can also hold my inflator, 2 cylinders, levers and spare tube.Oh, use the included rubber sleeve as the cylinder gets freezing cold when used.

I ordered this CO2 inflator set a few weeks ago to round out my seat pack flat kit. Unfortunately, it didn't take long until I had to use it. I got a flat just a few days later and everything worked perfectly. It was all very self explanatory and very easy to use and got my new tube inflated in mere seconds. I used the smaller cartridge and it completely filled up my standard road bike tire and there was plenty left. I imagine both cartridges will easily inflate a mountain bike tire as well.This package includes two CO2 cartridges and a converter that screws on to the end of the cartridge when you need to use it. To operate, just screw the converter onto the end of the cartridge and press the end of the cartridge onto the valve.All around, this is a very standard inflator set and is incredibly practical to carry with you on any type of ride.

Original review - Have had to use twice since buying. Works better than my last inflator and it’s so small.Update - I had 2 flats coming home from a ride. On the second flat as I start to inflate, there is a loud noise and I notice the rubber washer that was previously inside the inflator is now around my valve stem by itself. I had to ride the last 4 miles home very carefully on what turned out to be 45-50 psi on the front tire. When it works, this device is great. But if it's going to fail after a few uses it provides no peace of mind that you'll be able to properly inflate a tire in the event of a flat. I'm just glad I wasn't 30+ miles away.

This thing is well made, very compact, and quite easy to use. Works on both Presta & Schraeder with no changes or switching anything around. You can buy cylinders in bulk fairly cheaply (one 16g cylinder is enough to fill one fairly flat 29er tire).One big warning: be sure to wrap the cylinder with a cloth or foam, or wear gloves, while using it. When the compressed gas comes out all at once to fill the tire, the temperature of the cylinder instantaneously goes to like minus-a-gazillion degrees. If you are holding onto the cylinder when this happens, you're going to get a nasty freeze burn.
