CO2 Inflator Kits with 9X16g or 5 X 16g CO2 Cartridges, Presta and Schrader Valve Compatible, Bike Tire CO2 Pump, Included Insulated Sleeve

Works flawlessly. No co2 wasted at all. Easy to use. Screws straight onto the presto valve before or after connecting your cartridge. Seems to be built with good quality, and comes with spare o-rings stored inside if you happen to be missing one one the trail. It’s super small and fits in any bag making it super portable. I highly recommend this item I’ve used it to help fellow riders multiple times already and it’s still in perfect shape. Unlike a lot of the other brands where you use them a couple times then they are trash or forget how to use them after going long periods without this one is the perfect fit for any cyclist.

Perfect. Won’t leave for a ride without these

Works great, easily portable and works as advertised, even better I'd say so.I run a 27.5x2.4 Maxxis DHR II on my rear with Enduro cushcore and it can get it from flat to Rock Hard with about 30% of the cartridge remaining.

it doesn't work every time. when it works it works great.

I was out on a ride and noticed I must have picked up a small puncture or pinch flat on my gravel bike. Since I like to ride far out on secluded roads, I always carry a spare tube, tools, and this inflator since it's nice and compact. I was able to use this inflator to fill up a 700x45 gravel tube nice and quickly. I like the valve feature for getting the right pressure and the included sleeve since the cartridge gets very cold!

Great value and solid inflator.

I purchased this in January after a friend had a flat on a ride and we struggled to inflate her tire.Today i had a flat on a ride and this couldn't have been simpler. A few minutes and I was riding again!

Just what I needed... Will work great on long bicycle rides!!

Se ve muy bueno todavía no lo uso

I hadn't used one of these before so I have nothing to compare against but it works perfectly for my tubeless MTB tyres. Inflates instantly with a small regulator dial. Its so tiny too that it takes up hardly any room so great for portability. I bought some different branded canisters too which fit into it too. It's much easier and effortless compared to a standard pump. I would definitely recommend this product to others. It is good value for money if you are thinking of getting one.

Alles top

Lebensretter für unterwegs wenn man mal einen Platten hat und keine Pumpe mit sich führt.Der Reifen ist ruckzuck aufgepumpt. Möchte es nicht mehr missen.

I have only used this once when out on a mtb trail and got a puncture 10 miles from the car and it saved me a lot of time as it was getting dark at the time which would have been a nightmare.It is a bit tricky to start with and i wasted some air trying to get it to work but it still did the job well and gave me 20psi which was enough to get half way there then i used it again for the other half of the journey to get back to the car as it was getting dark and there was no time to fix the puncture.I am glad i had it with me as it really did save the day.
