    I used a CO2 canister for the first time a couple of weeks ago, and was instantly converted. It was very easy to use - just twist it on to the adaptor and it starts to inflate straight away - if anything a bit too quickly.

    I think the advantages are threefold:

    1. A canister is smaller and easier to carry than a pump - as long as you only have one puncture on your ride. Actually, I'm carrying a canister and a small pump.
    2. Using the canister makes it all much easier - no huffing and puffing involved.
    3. You can get a very good pressure - up to 130psi - from one canister.

    Mine are Genuine Innovations 16g cartridges, but I would image most are pretty similar.

    Maybe give them a try.

    And thats the rub

    Have a go at inflating a road tyre to 110 psi with the kind of pump that fits in a jersey pocket
    Its a hassle to be polite :)
    With a CO2 insufflator its peasy

    But then what do you do if you have another flat???

    In the summer I accept that when I have a flat I can happily sit at the side of the road and pump away by hand (ooo errr Matron) for hours till my tyre is firm (ooo err Matron) whilst blackbirds and Sedge Warblers serenade me

    In winter I would freeze to death and thus carry a CO2 insufflator plus TWO cartridges plus a hand pump
    I also run stupidly heavy armoured tyres to avoid punctures

    But the plus is that come spring I switch to PR3's, dump the CO2 and immediately feel 7kph faster!!!

    Cheers

    Pump for me - much more versatile - how many cartridges do you take ? My pump gets a good enough pressure without too much bother. The lezyne ones are great.
  • Pump any day......think mine is a TopPeak mini-pump double shot type thing (??) and although small, you can put the tyre back to almost normal pressure with a bit of effort (say 90-100 psi).

    Had a CO2 inflator and it broke on the ride when trying to use it....maybe just have been unlucky but I thought it was a bit useless.

    CO2 here.

    It's better in every respect except the one mentioned - repeat punctures.

    But given that I very rarely have punctures anyway, especially now I run tubeless, and that last time I had two punctures in a ride was about 8 years ago, that's a risk that is small enough to be insignificant.

    Apologies for going off on a tangent but I'm always interested in hearing first hand accounts from tubeless tyre users. A few questions please:

    How do the tubeless tyres compare for ride quality to a regular tyre/inner tube set up? Are you using tubeless compatible rims or a conversion kit? What tyres are you running?

    CO2, all the way, seen too many people furiously bashing away at the roadside trying to get enough pressure into their tyres to carry on.

    CO2 is just so quick and easy, just carry a few canisters, they aren't heavy.

    one pump - both options, here:

    CO2 is fantastic - i too was an instant convert when I saw it used - but with this option you still have a pretty good micro pump thats not just baggage when the C)2 cylinders have expired

    CO2 is better for unnecessarily polluting the environment at the expense of a few minutes elbow grease.
  • deswahriffdeswahriff Posts: 310
    ..I carry both....I use the pump (mini pump clipped to the bottle cage, it's really not a problem to carry!) to get a bit of air in the tyre to ensure its seated ok, then blast it with the CO2 to get up to proper pressure.
    I carry 3 cartridges, one inside the holder and two others with old inner tubes round them to stop them rattling in the saddle bag.
    ...and the pump is always there just in case.....
  • danowatdanowat Posts: 2,877
    Yeah, because the manufacturing of tyres, innertubes and hand pumps is really environmentally friendly :roll:

    If you read my post, I said "unnecessarily". I would argue that Tyres and Innertubes are necessary to ride...

    Co2 vs pump makes no difference to riding, just convenience after fixing a puncture.

    the only problem I have with CO2 is that you have to deflate and reinflate your tyres when you get home because they go down a lot more quickly when filled with CO2 due to the solubility of the gas in butyl rubber.

    Touch wood, I've not had two flats on a ride before (except oddly, the other day for the first time - but the second one came less than half a mile from home!).


    I only carry one spare tube anyway, so not sure how a pump would help me with having more than one flat on a ride.

    So I go for CO2. I have a little pouch that holds my tube, pump with cartridge, money, keys, levers, multitool. Fits perfectly in jersey pocket (and is relatively flat).


    However - if people can recommend an excellent, small and affordable mini-pump - I;d be interested.

    If anyone is in the market for some CO2 inflators, Wiggle are knocking out all the SRAM ones on the cheap. It is just rebadged Genuine Innovations stuff as well.

    Pump and CO2 have their place...

    I use CO2 when racing, if I puncture I can get back up and going quickly. If the conditions are right I might get back on the bunch and at the very least I don't get a DNF. But I also carry a pump so if I get a second puncture there's little chance of getting back on. But still I try and avoid a DNF.

    For any other situation; training, commuting etc I always rely on a pump for reasons already state.

    Genuine Innovations make a dual pump!

    CO2 AND a mini-pump in one. So you can use CO2 the first time and still have a mini-pump in case of second/further problems.

    This seems to be pretty good: http://www.bikeradar.com/gear/category/tools/cycling-tools/mini-pump/product/review-bontrager-air-rush-road-pump-10-39705/

    Also been toying with the idea of pump vs CO2 but didn't want to carry it on me, this seems it would do the trick nicely!

    I prefer the feel of them. You can safely run them at 90psi so you get good grip+feel+comfort but they still roll well and you don't need to worry about pinch puncture issues like you do with clinchers at that psi. Some people like running their tyres a 110+ psi and good luck to them but for me the ride is [email protected] and the grip is compromised too. Maybe if you live in France...

    I run Hutchinson Fusion and Atom tyres on both tubeless rims (Dura Ace 7850SL) and std Open Pros taped up with Stans 21mm tape. Both work fine.

    The only reason I run clinchers now is due to cost, through the winter, as the tubeless tyres are twice the price of, say, a Mich Krylion or Conti gatorskin.

    For all other times it's tubeless all the way.

    @ maddog 2 - Thanks for the all the info. I've had a pair of Fusion 2s and a conversion kit sat in the shed for over a year. I reckon I'll try it out when the current tyres wear out.

    Quality thanks for that :D ...and they work out cheaper then the G.I one I have :D
  • maddog 2maddog 2 Posts: 8,114
    I don't use a rimstrip by the way. I just tape the rims up with Stans tape - or 3M crossweave which is much cheaper - fit the tyres with a bit of sealant, then inflate them on a compressor. Once you done it once it's a doddle.

    I also run some sealant round the bead with an old toothbrush prior to inflating, just to help them seal and hold air.

    there are a few different types on there which one should i go for?

    threaded/nonthreaded/twist/race etc etc?!!! :?

    got the trigger version as have the G.I one and its great :D ....am a little sus of the "race" ones...nothing to grip to other then a freezing cold cartridge, and no regulation of the flow = not a good thing when your in a rush lol. The G.I ones are really well made...heres to never needing to use this one :lol:

    The SRAM race ones come with a rubber sleeve to fit on the cartridges and once the head is screwed on you just twist the cart back a fraction to regulate the flow or turn off.

    I use this one: http://www.wiggle.co.uk/sram-trigger-no ... lator-red/

    Trigger Non Threaded. Cartridge fits inside the holder (upside down until you need it - then just screw it in). It's not the Lightest - but works really well and is very solid. £9 is a bargain.
  • Both have their merits.
    I liked using CO2, but I carry a pump now.
    At least with a pump there is no limit to how many times you can use it.
    However in terms of ease of use, the CO2 wins.

    My co2 cannister was a disaster (or my ability to use it perhaps!)

    When they work they can be great but having had a dud cannister, I decided to stick with a leyzne pump which works every time and provides a decent enough pressure.

    P**ctures don't always come in isolation hence I carry two tubes and a patch kit.

  • Since you carry more than one tube surely you carried more than one CO2 can?

    I don't understand why people assume you can only carry one CO2 can around. My Ultraflate has one fitted (just twist it to break the seal) and I carry 1 or even 2 extra in the saddle pack along with a spare tube (and a tube in a pocket). My CO2 gun even has a trigger so I can control the flow (and don't get frozen hands).

    Gave up with pumps about 5 years ago.

    Frankly if I get more than two punctures, I'd give the day up as a bad job and get a lift home/sag wagon. The fun would have well and truly gone out of the ride.

    What do you do if your pump breaks?
