Does the sealant harden after a not very long period of time? How do you change the tyre, will the rim be covered in shite? Also is there some faff involving having to put pressure in rapidly when first installing them?
Yes, yes and yes. Still worth it.

A + in chemistry. It must be around two years ago now at the bike discount shop when I had everything tubeless in my basket and bailed out on the way to the till. Not worth it if you do just 10k in and around London.

So what happens when the sealant hardens, you have to change the tyre?
-

It evaporates after about 6 months, so when you come to renew it there won't be much left in the rim at all.

If you've been riding rather than storing your bike, it forms a thin layer on the interior surface of the tyre. You keep adding new batches until the tread wears out, which will probably only be once or twice if you ride a lot.

So instead of a common tube, I'm carrying sealant, valve cores/tools, syringe? Pass.

Why?
My use case is 6700k across the USA as fast as possible carrying as little as possible and all the training leading up to it. Not pootling around London, not MTBing.

nope, you carry a spare tube but are much less likely to have to deploy it
(i also carry a rubberized superglue that i have successfully used to seal large cuts and then carry on riding after simply pumping up the tyre again)
-

I'm still using tubes on my road bikes. I'm in no hurry to convert. I might look at UST rims when I wear out the existing rims. In like five years time then.
Cross and MTB get the tubeless shiz for additional durability and low pressures.

So, I'd lose two tubes, add liquid, but still carry spare tubes... which then I can't fit, because tubeless? :)
-
• #7238
it is no problem to fit a tube inside a tubeless tyre/wheel combo
plus you will be unaware of all the punctures the system does seal for you

I heart Conti.

It has definitely been a problem for some.
Read the tubeless thread.

• #7244
People struggle to mount tyres tubelessly with a hand pump but it is normal routine if using a tube.
-
• #7245
Just had a quick skim of the tubeless thread and read some tales of washing up liquid to mount tyres, squirting latex and sidewall patches made of old tyres. Fuck that shit, I'm happy with inner tubes and the odd "possibly prevented if was tubeless" puncture here and there.

Nope, as you don't need any of that stuff. Small holes will be sealed by the sealant, large holes you fix using a tubeless repair kit:
Which looks massive in that picture but is actually very small.
You stop, shove the pointy thing in through the hole, pull the device back out leaving the sticky rubber bung in the hole, then pump the tyre up again and you're on your way.

I've only used the Schwalbe "Tubeless Easy" tyres, on tubeless ready rims - and they seat and go up with a standard pump. Once they're on you never take them off until the tyre is dead as you can fix punctures with the tyre in situ.

Tbf, these 'tales of woe' are where people will insist on trying any old tyre on any old rim. Tubeless ready tyres + tubeless ready rims + decent track pump = easy.
It's the mixing, matching and bodging that's going to be causing all the headaches.

do tubeless also offer better rolling resistance compared to butyl tubes? How often do you have to pump them? Can it be ok if kept unattended over winter?
I'm just an old dog that doesn't want to learn new tricks. And I hated chemistry at school.

Sorry, am noob.
