Just curious...
Which you do you prefer and why?

• CO2 cartridges
• Frame pump
• Pocket pump

Thanks.

WhyFi

Tubeless.

mrblue

I've been considering that option since I have a set of Reynolds that are TLR but have been too lazy to deal with it. However, I've heard even if you are running tubeless it's a good idea to carry a spare tube just in case...

Mini/pocket pump. I don’t like the idea of CO2 cartridges that are single use and waste resources. 40 years cycling and mini pumps have yet to leave me stranded.

GlennR

I carry CO2.

I also have a second bike with tubeless..... ever see the inside of a tire after it was filled with sealant? Not something you'll want to do on the side of the road. Also the bead on a tubeless tire is much tighter than a clincher so good luck getting it off and on. I stopped carrying a spare tube and levers on my bike with tubeless tires.

It's not that dramatic. I have repaired countless tubeless tires on the side of the trail on MTBs over the years (and one badly cut tire on a road bike). Unless you are running an exceptionally tight rim/tire combo, it is not an issue. Tubeless tires still get cut and flat. There is no way I would go without the basics to fix them. There is a little bit of mess but it is a ton better than walking...For the OP, I carry CO2 but make sure to release it and replace with air when I get home. CO2 and sealant can react badly together causing the sealant to fail when needed.

For many wheel/tire combinations, it is an issue.

Pizzaiolo Americano 

I don't know about "many" but I know there are some. That is why I put the disclaimer in there. The worst I have run across are Mavics or Trek wheels that have the rim strips in them.

Too many dollars chasing too few goods.

Put me down for frame mounted mini pump.

WhyFi

Yup. This is usually something said by people with little/no tubeless experience as they parrot stuff said three or four years ago. I still haven't come across a combination that needed a lever to install (though I've had one combo that was a bear to break the bead lock until I learned the proper technique) and they've gotten easier to mount every year. I'm sure there are some bad combos out there, but the concern is overblown and usually voiced by people looking to justify their own decisions.

I run tubes. Carry a Topeak Road Morph G, 2 tubes, patch kit, boot kit, and also tire levers for other people's bikes. And a spare tire. I've used all of it.

caloso

I carry both CO2 for the first flat, and a pump for the second and subsequent flats.

deacon mark

I carry CO2 but they are not infallible. They can be hard to fill when it is cold and you could not get the co2 in and lose all the gas. So I have a small mini pump in the bag too and this really is enough it will get the tire to where I need it to ride 75 psi or higher if I work hard at it. Endless air the only reason for co2 is it can be faster.

10 Wheels

I carry 5 spare tubes, one spare tire, Topeak pump, and CO2 for when it is hot or raining.

C02 is quick and convenient and also single-use. I don't like single-use packaging generally, but more specifically i don't like single-use necessities .... if I carry two cannisters and one misfires and the other barely gets me to riding pressure .... what do I do when I get a second flat?

I have a mini-pump on the frame iof every bike---nothing is less fun than buying a nice pump and leaving it home on the one day you need it.

There are a few pumps I have found which really get the job done ... and some that are arm-breakers.

I carry two tubes ... and sometimes glueless patches, just in case. I only carry a spare tire when touring.

Pb_Okole

I use both. If I am alone and in no hurry, I will use a pocket pump. If I am with a group and don’t want to slow them down, I will use a CO2 inflator. Each bike has a small seat pack with a tube and two CO2 cartridges and inflator. Pump and another tube in jersey pocket.

bruce19

Tubeless. But, I do carry a mini pump in my back pocket. I have 2 bikes with tubeless and my GF has one. In the past 2 yrs....zero flats.

Steve B.

At home, a floor pump for inflating prior to a ride
On the bike, a bunch of CO2's plus a mini-pump in case of a flat.

Tubeless as well as tube tires need air periodically and right before a ride typically. Easier to do with a floor pump. CO2 is emergency only.

Branko D

A very miniature pump in the saddlebag and a spare tube and patches just in case, but I've also taken to carrying a Vittoria pitstop canister which is supposed to both seal minor punctures and reinflate the tire.

Since most of the time is consumed getting the tire on and off that sounds like a good plan A, but I haven't had any flats in a while to test it.

MattTheHat 

I’m at about 15,000 miles now of not carrying any inflation device while running tubeless. YMMV.

MattTheHat 

And I"ll probably get a flat tomorrow.

GlennR

I went 4000 miles flat free and got 2 in a week.

That right there is why no one I know(in the Phoenix area) uses GP4000SII tires. They are fast and somewhat comfortable, but have a long history of getting cuts like that.

Michelin Pro4 SC have the same reputation around here.

GlennR

26,000 miles and that was the first time I had a cut all the way through.

But GP4000SII are discontinued so lets wee of the 5000 are just as good.

noodle soup

I used to use GP4000s and Michelin Pro2/3/4SC tires, but Phoenix made me change. I had too many tires cut like that. I went to Pro4 Endurance tires, and thought I found "the one".

Something happened though. I think the city or county started keeping the streets more free of debris, and cuts became infrequent.

Thorn puncture will always be an issue here, but tubeless solved that for the most part.
