• Over there on the regular tyres thread, we've been having some lol bantz about my adventures in tubeless.

    I am left with a question, though. In fact two:

    how common is it for sealant to jet out of a puncture hole like a fountain? With road tyre pressure, I'm guessing this may be fairly common.

    Is there some kind of technique for getting a puncture to seal? The hole wasn't that big but it seemed that the tyre flexing under load made it unseal.

    I'm in two minds as to whether to repair the hole and go back to tubeless, or just keep the inner tube in.

  • This is when the tubeless worms can be useful. It sounds like too big a gash to seal.

    Or when you stop make sure the hole is at the bottom so the puddle of sealant stops air blasting out. Then the sealant has some time to set. I have deployed this technique a couple of times.

  • Perhaps I should have left the wheel "hole side down" for longer.

    My reaction was to attempt to stop the goop from pouring out, but thinking about it, that doesn't make a lot of sense.

    Marathon supreme tubeless on commuter bike have been fine so far, so I currently have mixed views.

    Debating whether to go G-One tubless or Corsa G+ / latex tubes in the Isen.
