If you have tubeless wheels than all you need do is fit UST or tubeless ready tyre, add sealant, and inflate… you shouldn't have any of these ghetto tubeless woes.
I guess it's because I tend to hear various tubeless woes, but in return people get fewer punctures. Given I rarely get punctures (not many thorns in the Pentlands) then there doesn't seem to be any point.
I've got a set of the Specialized 2Bliss tyres on another bike so could give tubeless a try, however it seems like a bit of a faff to solve a problem I don't have.
