Co2 pumps

pete600

Hi was thinking of Co2 canister instead of my mini pump. What i want to know is when you get a flat you have to pump up the tube a bit to find the hole. Can you do this with a Co2 and still have enough Co2 left to pump the tyre 100psi. Or do you just get one shot with the Co2

Thanks

I bought one but was not that impressed. I used it on my mountain bike when I went through a spate of flats. It blew the tyre up just once and was then empty. Not so good if you then find that there is more than one puncture and then need to blow it up again.

I ditched mine in favour of a small stubby pump that fits inside my small saddle bag.

depending on the model, it can have a trigger to 'control' the air flow. but it blows up so fast its hard to control it and you'll end up wasting a lot of co2.

co2 pumps can be handy but always carry a mini pump too. sods law states you will get n+1 punctures where n is the number of co2 canisters you have!

I carry a spare inner tube always if I go out for a ride. When I commute I carry a spare inner tube plus a spare folded Michelin Carbon as I need to carry other stuff so the tyre makes next to no difference.

I look at CO2 as a compact tyre infaltion option to pump up my tyres in an emergency ( ie carry on riding/get home/get to work). I find getting a high pressure with a hand pump a real pain and then you risk damaging a rim if yoiu have low tyre pressure.

I use a large hand pump at home to pump up my tyres to the correct pressure or to repair inner tubes ( cannot bear to get a single puncture and throw away, seems a waste) and would never waste a CO2 bottle to check a tube out.

Thanks for that guys. Think i will get a Co2 pump and as Merlinghnd says carry a extra tube.

Thanks again

Carry a spare tube aswell as the CO2 rather than trying to patch, as you'll lose too much CO2 trying to find holes.

To inflate the tyre a bit to help installation, use presta valves and just inflate with your mouth like you would a balloon.

Don't forget to check the inside of the tyre and remove the offending thorn (or whatever), otherwise you will puncture the new inner tube in the same place (or even puncture through the patch )
