co2 cartridges.

co2 cartridges.

I've been wondering about co2 cartridges, on a 700x28 tyre at what pressure does the tyre and the co2 cannister equalize? I'm not really expecting anyone to know this, i was just wondering.

Short answer is... it depends on the size of the CO2 cartridge

 

[smokeysmoo]

Any better other suggestions?

I can wholly recommend the ROAD MORPH

Wow, that is brilliant. Now i just need to work out what size my co2 cannister is. Just out of interest do you know why they bother making the 45g one?

I've not used a c02 cartdridge....

...so if my tyre just needs topping up...and not a complete inflation are these still an option?

An HPx will get you up to 130psi, but it starts to get hard work past 100.

CO2 cartridges are single use. Many inflators have a trigger for control, but it's not intended to prevent leakage over several days.

Note also that tubes are more porous to CO2 than to air, so you'll lose pressure over a comparatively short time. At a guess, if you had a puncture and inflated to 130 on CO2, you may be down to 110-115 by the following morning. It's not a problem at home where you can reinflate with a track pump before your next ride, but not so good on tour.

I use a topeak pocket rocket, it makes it to 100psi extremely easily (I stop there) and the blurb promises a max of 160, I can imagine 130 would be definitely do'able but that you'd be pushing quite hard on it by then.

it grips the valve well, locks solidly & sits nicely in the hand in use.

Cant get my topeak pocket rocket past 90 psi with wait for it 200 pumps! I use some zefal that I found lieing in the road

I carry a Topeak pocket rocket, but have a few co2 with me

I cant really see that a 'short' pump is going to work ...not to get back up to high psi anyway. I like the look of the road morph.

I have a road morph for my commute bike, brilliant bit of kit but to 130psi? Hard work with anything other than a full track pump I would think!

The 45g seems to be more for motorbike/ATV tyres, it's also got a different tread to all the others. I'd removed the motorbike/ATV section from the chart I posted as it's not relevant in this parish - full version is here

could be faulty, ? the seals aren't sealing.
