out of curiosity, my tyres are now tubeless.
thanks to luck/tubeless, i haven't had a puncture in about a year.
to minimise faff, i only carry 1 tube, and it's a 28er (yes).
back in the good old days i'd hand out tubes to any poor soul who needed them. (i carried 2, so i didn't snooker myself)
but now, even if my 28" tube fitted their bike, i'd be reluctant to hand over my tube - sod's law dictates THAT would be the ride where my tubeless experiment failed.
interesting... a combination of tubeless, and wagon-wheels, has turned me into a git.
Also Tubeless here and like you largely without incident for quite some time (touch wood).
I still carry two tubes (26") and some Park glueless patches, my logic being, that if one UST tyre goes, the other is still potentially the subject a separate failure, and tubes are still the best get home option, hence I carry two tubes, I also carry the patches as an extra, extra backup just in case having had to fit both tubes I then pick up a hole in one..
The patches weigh barely anything and are simple enough to use, TBH though I've not had to resort to using them since going tubeless and only had to use one tube to re-inflate a holed tubeless tyre.
But think about it, what's the worst thing that could possibly happen on a ride?
Say you run over something big and pointy enough to hole the front tyre, who's to say it won't catch the rear too? - Ride over without a means of repairing both.
Or you get a front flat 10 miles in fix it with your one tube, only to get an un-fixable rear flat 20 miles into a 30 mile ride, you're ride is knackered all for the want of a couple of hundred grams of Butyl...
It's a bit like playing rock, paper, sciscors I know but how else can you mitigate something as random as flat tyres?
Of course as soon as I hand over a spare tube to a stranger in need I potentially open myself up to a similar fate too, maybe I should carry three or four tubes, just to be on the safe side
