    I’ve recently dumped the mini-pump in favour of a CO2 inflator and cartridges. How many cartridges do you tend to take with you on say a 60 mile ride? I’ve been known to get a couple of punctures on shorter rides and would be a little nervous if I had no back up.

    Also, does anyone know a supplier of cheap cartridges (16g)?

    Thanks

    reading up on it it appears the co2 molecule is soluble in rubber hence the deflation. This is certainly my experience.
    Must try the fresh air every ride, I’ll compare times 😉

    Filled my wife’s front with co2 after a flat, then rode home no probs. She took the bike the following week and tyre was flat. I hunted for the hole but the tube was perfect, so there might be something in that theory.

    Not convinced about that.
    Not convinced about that. Nitrogen atoms and oxygen molecules are smaller than CO2 molecules. Nitrogen is used to inflate tyres of racing cars, apparently – if it’s good enough for them, it’s good enough for me.

    For the record, I carry three CO2 cartridges, last lot bought off Ebay – box of 30 for £20 – should last for a few years …

    What? Don’t you deflate your tyres after every ride anyway? I do. I let all that stale air out and put a nice fresh lot in before I set off the next time. It makes me much faster.

    Can’t argue with that. Sounds like Science 😕

    This may only be in relation to mtb tubeless set up’s as it can turn the sealant into globby gunk.


    I find that tyres inflated with Co2 go down, sometimes overnight. Maybe the molecules are smaller and migrate through the tube wall?
    I always re inflate with a track pump after a repair.

    Don’t know about any migrating :/ , but I do know that it’s advisable to repump the tyres to their former 11 bar glory when you get home.

    I carry a couple. Tend to use them when the weather is rubbish and my hands are at risk of dropping off. Always carry a mini pump regardless. There’s some really good ones out there. I’ve one of the blackburn ones can’t remember the model and it serves as a get me home. As jimmo says – make sure the tube isn’t likely to get pinched.
