hi all just wondering if anybody has tried a 25g CO2 bottle on there road bike tires & if they know approx what pressure it inflates to ?
i use the 16g CO2 bottles now & find they only inflate to around 80 psi i normally run around 120psi in my road tires & am thinking if these 25g Co2 bottles would inflate to around there ?

your question articulated what I had wondered myself.
A troll on the net found this

Also an interesting article about aircraft pressures and CO2 cartridges.

Good links thanks. Used a 16gm cartridge for the first time yesterday and it pumped up a 23c tyre hard, felt like well over 100psi.
Given cartridges are banned on aircraft, where do people buy them from at a reasonable price?
bollo, I haven't had tons of experience with the CO2 cartridges, but I'd be shocked if a 23 or 25 wasn't sitting at 110-120psi... I normally run a slightly lower pressure and notice that after a CO2 jobbie they are like iron to ride on. Issues with the CO2 pump? (I am pretty sure mine is cactus right now)
warthog - try finewhip.com (no, it is not some kinky site, but may raise a few eyebrows amongs your IT staff if they just look at browser history!!)
get mine there - cheapest I have seen (apart from when cell etc do a ridiculous deal). they are around $40 for 30 cartridges from memory
they are not banned on aircraft in carry on or checked luggage (virgin) - i have had no problem checking them in when taking them to triathlons. see virgin guidelines about bikes halfway down the page

+1 for Cell on C02 sales.
Also, the 25 & 32g ones never se to be cheap, so I budget using two 16g ones on the MTB (if in a race or am in a hurry for other reasons).

Why do you run them at that sort of pressure? Are you a clydesdale?
For my 78kg I run my 23c Conto 4000s at 95psi for the rear and 85 for the front and it rolls great, great cornering traction, and best of all I'm not popping spokes or shaking my teeth loose.

Thanks for that I'll check them out.
I don't fly anywhere so had no idea about luggage regulations. I was going off the Velonews article earlier in the thread.
I figured that meant that the usual o/s online stores wouldn't sell them due to inability to airfreight them?
It s a weird one bollo - you checked the wheels are true and everything is ok with the wheel? I've had terrible trouble with low tyres and it was actually wheels out o true and badly adjusted brakes. I doubt it is an issue bu some thing to consider.
