CO2 pumps

[raf_gti]

Aside from killing the planet are those CO2 cannisters any good?

I quite fancy getting one to use with my road bike but have a slight paranoia that they will only inflate to half the required pressure or just be generally st.

Not sure they're fossil fuelled...

My issue with them is that they don't replace a pump. What happens if you get multiple punctures in a ride and you've used up all your gas? I've had rides where I've had 3+ punctures - very annoying but ok if I've got a pump and puncture repair kit.

Edit: maybe I'm over cautious...

Good solution for unsupported long-course racing; fast fill to consistent pressure - assuming you're competing at such a level that more punctures than you have spare tubes will ruin your day anyway.

A lot of people use them in conjuction with goo-filled tubs, too, whereby in theory you can survive as many punctures as you have CO2 cylinders.

Not sure they're a substitute for a pump otherwise: and I'm certainly far too slow to worry about them.

As above - no substitute for a pump. I always carry them though as its so much quicker, good for racing.

I also use them for fitting my tubeless tyres.

I've found they are fine for that day, but the tyre goes soft over the next couple of days. Draining the tyre and pumping it up properly when I'm home stops this from happening...
