I only get flats when I neglect to bring a tube/repair kit with me

Well you did it the Fred way with Co2 then and since co2 isn't stable in a bike tire and leaks fast, congratulations you will just have to repump the tire anyway in the next few days. Of course that time seem unbelievable in general for a fixing a flat on the road.

See:
>http://www.exploringoverland.com/overland-tech-travel/2016/3/25/3izopxom72k7p3vxpvjtfuhk7ouscc

>Some years ago racing bicyclists began carrying tire-repair kits that used common miniature CO2 cartridges to refill a patched tube in seconds, saving the time otherwise wasted using a manual pump. The kits subsequently became popular among recreational cyclists who weren’t necessarily in a hurry, but simply couldn’t stand not having the latest high-performance gear, or felt that the drudgery of working a manual pump was simply . . . hell.

>Soon, however, riders began noticing something: The tires they filled with CO2 seemed to lose pressure much more rapidly than when filled with air. Some claimed a tire filled to 90 psi with CO2 would be down to 40 in a few days.

>... A CO2 molecule is larger than either a nitrogen molecule or an oxygen molecule, which together comprise 99 percent of air. How could CO2 leak out faster? ...

>Finally a few people familiar with chemistry looked for an explanation, beginning with the properties of gas permeation by diffusion. All gasses exhibit a permeation rate through butyl rubber—the material used in most bicycle tires—proportional to the inverse of the square root of their molecular weights. Using this formula, you can show that the rate of permeation of CO2 through a butyl tube compared to air should be . . . uh, well, lower. Hmm . . .

>Finally someone got it. The answer has nothing to do with molecular weight, although it is still a chemical phenomenon. It turns out that CO2 is actually soluble in butyl rubber—it essentially melts right through the material without having to wait for permeation.

I'll rather fill my tire with co2 instantly on the road and then empty and refill it again with air once I get back home with a proper track pump. I don't know about you but pumping tires with a mini pump at the side of the road isn't one of my favourite activities.

not sure what you’re snorting, but cartridges exist so you can get home, without carrying a ridiculous frame pump. you don’t use them for routine top-ups, they are the counterpart to a patch kit or spare tube

I carry co2 because if I get a flat I don't want to be late for work. I'll pump it up when I get home. Not really an issue

it’s funny because the tripfag thinks everyone here is a weekend strava roadie, the only kind of cyclist they have in suburban NJ

I took the carbs off my EX250 in under 10 minutes one time.

Unbeknownst to me at the time I had a leaky gas cap so I got a lot of practice.
