You know the drill
So you're out on a lovely bike ride miles away from home you're in a group and the dreaded happens, you get a puncture. Could be even worse, raining too! So you know the drill, rear wheel out, tyre levers out, remove inner tube, check for thorns, put a new tube in, put the tyre back on the rim and start pumping, a lot. Now bearing in mind you need to try and get 100psi back in the tyre using your hands only, this can only mean three things. Very tired arms, minutes of wasted time and not enough air! Now there is a solution to this awfully long winded process... And that is the wonder of the co2 canister - a couple of these fast release air canisters make a 10-minute job into a 10-second job. Not only is it a lot quicker, less tiring but also gets a lot more air in the tyre. You are soon back on the road and your club mates are even happier that they haven't had to wait for ages for you to pump the tyre up. No one has got bored or cold in the process and you are back eating up those miles.
What is in Co2 canisters
So if you didn't know, you can get co2 canisters in a few different variation of sizes and often come in packs of 2-5. A 16 gram canister is capable of inflating a road tyre up to a whopping 120psi and a mtb tyre to 30psi, so this is more than enough, plus a bit more, to get you back up and on the road or trails.
Few things to consider
When using co2 canisters you have to be aware that they get very cold upon releasing the air, most canisters come with a protective sleeve to ensure your hands don't get stuck to the canister! Even though these canisters are great, just remember if it fails or you happen to get more than a couple of punctures, (unlucky you would be if this happened) but always carry a pump in case of emergency. You can never be too careful. There are some great tools now in which you can buy that do the best of both worlds, The hybrid pump is the perfect tool to carry.
Canisters also work great and are often preferred if you are running tubeless. Since there is sealant in the tyre most little thorn punctures seal up on there own. But if you are unlucky enough to get a big hole in the tyre and you lose some air before it seals again or you the tyre rolls off the rim you simply use the canister to fill the tyre with air quickly and this often resolves any issues when running tubeless. If you like to be extra cautious, take a tube with you just incase you rip your tyre and it cant be repaired with air and sealant. Sometimes putting a tube in can help you get home in an emergency.
