Having no background in mountain biking, I’m naturally suspicious of the idea of tubeless road tyres and I’m in no hurry to try them out, despite being offered them by a sponsor. Most of the people that I know who’ve tried them rave about them, but I also know a few people who’ve punctured with a hole that was too big for the sealant to fix and they’ve ended up coating their bikes, themselves and anyone following them with liquid latex .
We had Edco as our wheel sponsor a few years ago and their wheels were tubeless-ready. Our tyre sponsor at the time didn’t produce a tubeless tyre, so we just used them with regular clinchers. They were the tightest-fitting tyre/wheel combo that I’ve ever experienced and almost impossible to fix a puncture on the roadside. To make things worse, you had to pump them up to over 120psi to seat the tyre and then let out the excess pressure. The tyre made a distinctive “ping” sound when it seated. Once seated, it was as if the tyre had been glued to the rim and it was a real mission just to separate the tyre from the rim to replace the tube, even with the tyre fully deflated.
