CO2 Inflator or 12PCS X 16g CO2 Cartridges for Bike Tires, Presta and Schrader Valve Compatible, Bike Tire Pump for Mountain and Road Bicycles, Included Insulated Sleeve

I can't rate this item highly enough! Incredibly easy to set up and use. Small enough to fit pretty much anywhere you like, but big enough to be easy to use. It's the first pump I've ever come across that actually screws onto the tyre valve, with a clever system that fit both Presta AND schrader valves without need to adjust it. The only way they could possibly improve the design is to incorporate a pressure gauge. 5 STARS ALL THE WAY!!!

Works a treat for fast tyre inflation with easy control. Small so easy to keep in pocket just in case. Use gloves as cylinders can cause freeze burns. I never ride without it.

This is the second one i have purchased. I have one in each bike, absolutely brilliant, and right up there against Lezyne products, (also owned).

Works well

Works great to re-seat tubeless tyres.

Perfect

Product was robust and easy to shut off with no leakage. Far better construction than the Ballihoo version .

Well made. Better than the muc off version which I had trouble with, as it leaked soon as a cartridge was screwed on. Only issue I had which was minor after the first use. I found if you don’t turn the dial quickly not enough gas comes out to inflate the tyre. Worked second time I used it fine. Just turn the dial really quickly and it’s all good
