GEWAGE CO2 Air Pump for Bicycle Tyres - Includes 4 Pack CO2 Capsules 16g with Thread, Compatible Presta & Schrader Valve for Mountain & Road Bikes

A must for when I'm on my mountain bike really quick inflation rate enough to Bead a tyre back on the rim if need be. Always carry this with me no need for a bike pump this is so much easier.

Good

Works really well

I have 29 inch 30mm so quite large tyres, had to take off rim for a bit,The CO2 inflated was very good at re-seating the tyre,I had to pump it up to proper pressure with a more traditional pump, but the CO2 inflated got it from 0 to near 10 psi in about 1 second, so quite handy to have.

I've bought these before and they've not worked, just left me with frozen fingers, this works great, used it to pop my tubeless tyres in place, awesome!

Not sure if I was doing anything wrong but the O=ring popped out of the device the first time I used it. I was unable to put it back in and unfortunately stuck on a trail. I could no longer get a seal and by the time I was on the 4th cannister it had split. Not sure it is of any use to me now.

I run a tubeless set up on my mountain bike.. I changed the sealant inside my tyres which involved removing the tyre from the rim.. put the tyre back on and a quick blast and tyre seated and sealed on the rim.. perfect

Good product
