  • Yeah I've just shot them an email. I can imagine sealant being an issue if you get a flat, but if you run it dry I'm not sure how it is any worse than running clinchers. If anything a tubeless tyre when used with a tubeless rim is harder to demount than a clincher when flat. Even then in my 8 or so years of running tubeless, my experience is that they tend to deflate quite slowly, as opposed to conventional clinchers which tend to deflate instantly when punctured

  • but if you run it dry

    So no tube, no sealant? Will they hold air like that?

    The sealant is the issue so yeah, no sealant, no issue.

    That said, if your tyres are tubeless then they probably aren't track tyres? Road tyres are, again, probably fine at HHV, not so at an indoor velodrome.

    Withdrawn. Looked at the tyres you're using and, that must be about the only tubeless, track tyre there is right?!

  • Yeah normally I will use a bit of sealant on initial setup, however once it seals (varies with setup) in my experience they are airtight from then onwards. They do tend to lose air more quickly than a tubed tyre but less than latex. I also tend to rely on tubeless plugs as well in the event of a flat, as I find they are much more effective than depending on sealant alone.

    Yeah I think that may be one of the few ones that is marketed for track although in this context for tubeless/clincher tyres it's not clear to me what that actually means other than a marketing term.
