This on my CX bike which I call my Gravel alternative. On my strictly road bike it's CO2 x 2, with spare tube and patch kit.

3x 100 PSI if you need it. Then just recharge before the next ride. I'm a convert. No bigger than a mini pump.
Learned something new, but i'll pass. CO2 works for me and if I get a 3rd flat, i'll just get a Uber home.

I carry both.
The hand pump is for general use, because you'll never run out of atmoshpere.
The CO2 cartridge is only for if I ever need to seat the bead in a tubeless in the god-forbid situation I ever get a cut the sealant won't seal & the bead comes un-seated. It's never happened, but most tubeless, if patched, will stay inflated with out sealant for quite some time...long enough to get out of trouble, anyhow.

I also carry a plug kit, & standard vulcanizing patches, a valve core, valve core tool, a master link, a multi tool, spare 2032 batteries for HRM/powermeters & a tool for the powermeter transmitter/cap. I should probably carry a chain breaker.

It all fits in a standard water bottle I transfer from bike to bike or put in my jersey pocket.

I carry a spare tube, a couple of 12g cartridges and a valve head in a small saddle bag, and a mini pump (in jersey pocket) for partial inflating the tube for installing. Had to use both cartridges once, when I didn't seat the tire correctly and I had to deflate and reinflate. I imagine I could inflate a tire sufficiently with the mini pump, but it wouldn't be pretty

Interesting tech, too bad it doesn't have a battery indicator that lets you know if you need to recharge it. Even if you don't use it the battery will drain over time. It's like a 3x volume co2 cannisters with a small leak.

These days we need an app to keep track of all the batteries we need to charge just to go for a ride :-)

I've always carried a pump. I think it boils down to your personal preference. A CO2 cartridge is great until you screw it up. Same for two CO2 cartridges. There are things you can do with a pump, such as limp home by re-inflating your tire several times, or inflating a friend's tire and having plenty left for yourself. There are things you can do with CO2 such as get back on the road quickly if your group is waiting for you.

Likewise, avoiding the "call of shame" at all cost is really an aesthetic preference for most of us, not a practical one. There are 4 licensed drivers at home in my house right now, and any of them would jump at the chance to go for a drive and mock Dad all the way home.

You guys with tubeless tires, haven't you ever had to top off on say a multi day tour? Or all all rides local for you?

I carry a minipump on all my 60 psi type bikes and a full frame pump on the two high PSI tired bikes. Lenze makes nice mini pumps with hoses that are either presta or schrader. The hose works as a schrader adapter for gas stations as well.

Always carry a spare tube since the day a tube failed at the base of the valve stem forcing me to scrounge and patch a discarded tube from the side of the road.

I get so few flats that the last time I did the tube of cement had dried out in my patch kit. Glad I had a spare tube that day.

How impatient are you? How easily to you get upset?

If you are the impatient type, CO2 is good because it only takes a couple of seconds to inflate your tire.
If you get upset easily, you might prefer a pump because it's important to have your wits under control and to make sure everything is right before using CO2. You only get one shot.

I carried CO2 only with me for several years with no b ack up and never had a bad experience. Now I've converted back to using a pump.

No manual pump, no C02. Brilliant.
Thanks for that; I have little girly arms and I can't micropump past 70psi.

Thanks for all the input, folks. I'm going to carry both.

I carry both a Road Morph and CO2 (2 cartridges). I never get flats near shade so CO2 during hot and humid days is a welcome relief. The pump is because you can never run out of air.

The extra few ounces also gives me a perfect excuse for not being very fast .

Don't forget to properly dispose spent CO2 cartridges.....ie. not tossed on the side of the MUP etc.

Wish I'd seen that before I bought the 30 pack of CO2 cartridges. I average 5 cartridges a year, so I'm set for a few more years.

And I'm in the 2 CO2 cartridge/pump backup group.

I just carry the CO2. I use the Genuine Innovations microflate style because it has no moving parts and has worked flawlessly every time I needed it. Never had more than one flat on a ride and when I do get a flat my protocol is to return home immediately. I do carry a mini pump on my mtb only because I couldn't find my spare CO2 inflator at the time and never replaced it.

Mini pump for the win!

I have gone with a mini pump because knowing myself I would screw up using the CO2 and not make it home. One time I got two flats in one day commuting to work and I was real glad to have the pump.

See if you can find a skinnier mini pump. A pump with a skinnier barrel will let you pump to higher pressures but it will take more strokes to pump the volume of air that you need to get full capacity.

i always tend to experience a sidewall blow out from something jagged on the road that is hidden in a wide crack only to spike up when the very delicate tire twitches its end, disturbing the jagged debris to attack to flat.
So I carry a tube & mini pump. I can get it up to 90% inflated to where it would normally be. Ditched the patches & glue long time ago. I noticed a lot more broken beer & liquor bottles around... so I might carry 2 tubes.

Doesn't matter. I mean, I carry both, but one day you'll find it doesn't matter what you decided. Eventually something will break you can't fix, and your phone will be either dead or in your garage.

Wear shoes you can walk in. Trying to walk miles in socks on pavement really sucks.

If I was racing I would use CO2, but since I don't race there is no need whatsoever to use CO2, and here's my reasoning for not using it.First off I don't like to do things twice, if you use CO2 to inflate after a flat repair when you get home you have to completely let all the air out of the tire and repump with air from a regular pump because CO2 will bleed air at around 50% overnight, so I'm not doing the same job twice. I also don't want to pay for air that I can get for free, I also don't want to be bothered with recycling the darn things, though most cyclists just simply throw the carts on the side of the road! Then when I use one I have to remember to either put another into my bag or go buy more.

So while that's just me about not wanting to use CO2, but for those that do want to use CO2 there are hybrid pumps on the market that do double duty, a pump and a CO2. Lezyne probably makes the best one called the Pressure Drive CFH.

I always carry a mini pump on the frame of each bike an a single co2 in the saddle bag. I don't distinguish between long and short rides and each bike has it's own stuff so I never forget anything.
