Haven’t read the whole thread so sorry if I’m repeating others..
Iaian, I converted 5 years ago for all of my bikes (except my road bike) including the wifes. I had my first puncture that didn’t seal itself about a month ago… in 5 years!
When I pulled the tyre off there was in excess of 20 thorns in it that had sealed never causing a puncture. The only reason it didn’t seal that time was I hadn’t topped the fluid up in 6 months.
It is literally in my opinion the best advancement in mtbs in the last 15 years along with dropper posts.
Punctures in the cold dark and wet are just no fun, so much so that the club I ride with every Tuesday night has pretty much banned people from riding with us if they are running tubes. Often in excess of 20 people out and we’ve had 2 punctures that I can recall across the whole group all winter. 1 of those was a guy who’s bike had come tubeless ready and he didn’t realise it had tubes in lol.
If you have proper tubeless rims and tyres then just pull the core out of the tubeless valve and use a compressor and they’ll generally go straight up unless your tyre is really baggy.
