So my new bike will have tubeless tires. Normally I carry a spare tube, tire levers and 2 CO2 cartridges.

What do you carry for tubeless? Does the sealant really work or do you have to remove the valve and install a tube?

The issue with fixing a flat on the road is that it takes a decent surge of air to seat the tire and make a seal. Short of that, the air escapes under the unseated tire as fast as you can push it in.

Road tires tend to be better than mtb tires in this respect, but you can still find yourself stranded. I don't know if CO2 inflators can do the seating job, maybe someone else can answer that, but if you are going to depend on CO2 make sure to carry extra cartridges since you can blow one or two in failed seating attempts.

Otherwise, carry a spare tube so if you have to unseat the tire, you'll have a plan-B to get going again.

After watching a few YouTube videos, it seems Plan B is the sure thing.

yeah, but you heard it here first.

I have been MTBing for a few years all tubeless. I carry an extra tube and CO2s. To date, I have not needed them. However, at home I had a couple of complete flats (mostly due to valve stems coming out). I had no problem getting the tires seated with my floor pump, so I have no doubt a CO2 would do it.

Not CO2 because most often when I get a significant puncture the tires lose some air before sealing so just need to be topped off. A mini pump works great for that. Just a few days ago I was riding and heard hiss, hiss, hiss as the front tire went around. I got off, positioned the puncture at the bottom and it sealed after blowing out some sealant. I topped off the pressure with my mini pump and it was a done deal. Of course if it hadn't sealed, I would have had to put in the spare tube and pump it up.

I have been thinking about going tubeless on my road bike so I try to read all of the "tubeless" posts but haven't made the change yet since the disadvantages still (to me) outweigh the advantages. That, plus I have seen several road riders stranded when their tubeless tires get a cut or slash too big for the sealant to seal and they didn't have a Plan B.

So I'm still on the fence, or at least looking over the metaphorical fence on the road tubeless issue. Anyway, thanks for the input everyone!

I have tubeless road, mtn and fat but it has not changed what I carry. I've had about a dozen punctures, mostly on my road bike (non on my fat which is used on snow) but none have required me to put in a tube. I carry CO2, tube, mini pump and repair kit because at some point I'll roll over mr.nasty and get a gouge my Stans or Orange goop can't handle. So far, however so good, including one day when I got home (on bike vacation) with four goat head thorns in my tire. Just a few days ago I got home and noticed Stans burped out of my tire. I had punctured and not noticed it. Can't tell I even lost any air at all. Tubeless rocks but with the fat bike I did end up having to get an air compressor that has turned out to be really, really fun and helpful in all sorts of ways.

My motto is it is better to have and not need, than to need and not have.

Extra tube, CO2 and a pump.

I betcha a six pac o beer If I was to leave my tube and tire tools home I'd flat my tubeless tires as soon as I was at max distance from the trail head.
You see,
Murphy and I have this gentlemen's agreement,,
If I do every thing by the book and am always prepared with a Hydration pack full of tools, spare parts, first aid kit and food and water I will have a great ride

I've learned not to break an agreement with Mr Murphy
I've fixed four flats on the trails,,only one was on my bike.. done with tubes now.
I've fixed two broken chains in the woods, none on my bike..
Tightened countless stems, seats and control levers In the outback,,funny, as always never on my bike...
