Aleric CO2 Bike Tire Inflator, Quick & Easy, Bicycle Tire Pump for Road and Mountain with Insulated Sleeve, Fits Presta and Schrader Compatible, CO2 Bike Cartridges Not Included

Had a flat tire today and this performed perfectly.

The inflator is excellent quality and easy to use. I really like the insulated sleeve to place over the C)2 cartridge so your hands do not freeze.

Pretty straight forward, screw it on the presta valve, screw on cartridge and unlock the unit. Co2 went everywhere but inside the tire, glad I was not out on a ride when I tested it out. Make sure you know how to use a presta valve first and open up the valve lol

He was happy with the gift! Be sure to get some cartridges!

I liked because is easy to use and small.

I had a flat while riding my mountain bike (tubeless set up) and well over a mile from my car. The first CO2 Leaked from the back where the on/ off lever is and the bottom. Figured that it was a faulty co2 seal so I tried another. Well three co2 canisters all did the same, leaked through the lever and where the co2 canister threads in. This left me stranded and pretty angry. I’ve had this inflator for awhile now and it was the first time that I needed to use it and it failed. Luckily I had a glove on when the co2 blew out everywhere

Not sure if it was just faulty or just badly designed, but it didn't work with Presta valves. Glad I tested it before I had to use it on the trail. It wouldn't tighten down on the valve at all. Works fine on the Schrader.

I bought this as a high pressure option to assure my tires are at pressure when I don't have access to a floor pump. It will be good for my needs.
