CO2 Inflator Kits with 6 X 16g / 25g CO2 Threaded Cartridges for Bike Tires, Presta and Schrader Valve Compatible, CO2 Bike Tire Pump for Mountain and Road Bicycles

good

You really want to carry a pump and be having to use it. These are life savers.

Just having to carry a top to the cartridges effectively saved 1 cartridge of space. It works great and the foam insulator allows it to be held while airing up.

Occasionally we all get a pop Tire it's always nice especially when you put slime in your tire to have an immediate solution this is able to air up 120 thanks tube or seven scooter tires with one CO2 also depends on how fat your tires are

I hate getting flat tires and I'll probably convert my bike to tubeless soon but in the meantime it's good to know I can pack these to inflate new tubes if I ever get a flat. If you've never used CO2 cartridges, they work so much better than the little hand-held pumps you can take along on the bike, Comes with 6 16g cartridges--the full amount will be a little too much for a road bike (I think it would fill it to 130 psi) but good for other (adult) tire sizes. This kit has a nice on/off switch to control inflation and even allow for inflating more than one tire with a cartridge.

EVERY Schrader pump has a center pin to physically open the valve spring. This attempts to open the valve with high pressure alone. It works to some extent but if you need to fill a 4" tire, one cartridge will barely reach a few psi. As soon as the pressure in the cartridge is less than the spring force, air stops flowing. This traps air in the cartridge that could otherwise be filling the inner tube.

The Good:-Comes with 6 cylinders-Valve has flow control switch-Comes with cylinder cover-Fits both common valve stems-Quality metal construction (aluminum?)The OK:-NothingThe Bad:-NothingThere’s a few varieties of these fill cylinder kits out there and for me it always comes down to the adaptor. They all contain about the same amount of CO2 and will get you going quickly if you need some air after a tube change or if you’ve just lost so much on your tubeless tires. The listed price is right in line with what I’d expect to see 6 cylinders for sale at and this set includes a very good adaptor. It appears to be made of machined aluminum and is very light. The flow control lever is easy to use and just having it is a huge plus for me. The adaptor fits both common valves and has an independent screw down ring. There’s nothing I can complain about with this set and I think they did everything in a way that would be great for most cyclists.

nice and compact little system to have just in case.I really like this idea. I'll be alternating this between pedal bike and motorbike. (along with a pressure gauge)I don't feel right giving it a 5 star because I haven't used it yet.
