Manual Transport CO2 Bike Tire Inflator, CO2 Inflator, Fits Presta and Schrader Bike Valve - CO2 Tire Inflator for Road and MTB Pump Accessory - Includes Insulated Sleeve - No CO2 Cartridges Included

I recently bought a pressure brake fluid bleeder that had a hand pump for pressurization. In the cool and very humid area where I live, I didn’t want to introduce moisture into the reservoir to contaminate the brake fluid. I installed a schrader valve fitting into the reservoir’s cap and use this inflator to pressurize the reservoir. The valve can be “cracked open” to regulate the flow of CO2. This couldn’t have worked better. Suggestion: when you order one of these, order the best deal you can find of THREADED cartridges at the same time as they can be hard to find (at a decent price).

I haven't had a chance to use it, but this is my first inflator that uses foam insulation. I'd ideally want a co2 inflator that has a precise tire gauge integrated (up to 40 PSI).I didn't leave marks for durability since I haven't used it yet (nor plan to use it often) but I'm happy with how tight the threads are for the cartridge. Normally threaded cartridges are made equal; somemhave tighter tolerances on the threads so finding cartridges that fitntight with this inflator will be the key to longevity.

Just recently received this CO2 inflator for a bike event on Oct. 19, 2019 and luckily did not have to use. Upon evaluation the inflator's build is quality workmanship with the control valve very smooth. I gave it a 4 star only because I haven't put it to use. I plan to try it out before my next bike event because I want to purchase a few more for gifts. I'm glad I saw this before I purchased another brand. Will update later.

Great price and outstanding performance! I have owned it for less than a week and used it twice - worked perfectly! The instructions warn you to not have a CO2 cartridge attached longer than 24 hours - my second usage was with the same cartridge 23 hours after the first use - it had retained pressure and was flawless in delivering the second set of pressure improvements.It is much smaller than you may believe - I know I thought it'd be more massive.

Great Product. I Highly Recommend this Product. Because let’s be honest who loves having a flat tire and not having anything to reinflate it?? This product will inflate your tires quickly and you will be back on the road in no time. Three days after receiving this product I actually got the privilege to put it to use and I had my flat tire fixed and my bike back on the road in a matter of a few minutes.

This thing is compact! I don’t have much space in my pack so I was glad this thing is smaller than I expected, as you can see in my photos (co2 canister not included). I have yet to actually use it to fill a tire, (hopefully I don’t ever need to) but it seems well made so I feel confident it will do the job. I like that it will do shraeder and presto valves without the need for an adapter.

Very good item

Flat tire at the side of the road. Couldn't get enough grip to screw the CO2 cartridge on hard enough to pierce it. Wouldn't work. At home, with dry hands and twisting it on as hard as possible, I could barely get it to pierce the cartridge. I wouldn't order this again. I've got other brands and have not had this problem.
