Anybody who cycles a lot will have had the experience of a flat tyre – it’s inevitable given the condition of our roads and cycle paths. So after you’ve repaired the hole you could:

a) spend 10 minutes with a hand pump trying to put a decent amount of pressure back in the tyre, or

b) Use one of these handy CO2 inflators from Topeak to blast gas back into the tyre without the effort.

The cartridges are strictly single use but they should last forever in storage and it seems like a far simpler way of getting the job done to me.
