I had a puncture during the bike leg of a triathlon the other weekend and used one of these Seal 'n' Flate things to try and fix it without having to replace the inner tube. It seemed to seal okay, but the flate bit was [censored] as it didn't discharge the whole can into my tyre.
I was running on a 650c x 20 Conti Grand Prix at 120 psi when it popped and I doubt that the can got it to half of that. Can I reasonably expect one of these things to inflate a 650c x 20 to a working pressure, or is it better suited to lower psi tyres...?

I expect its designed with lower pressure tyres in mind, and it's a "get you home" job rather than a racing product. But you could use the Seal 'n' Flate then add more gas with your CO2 inflator. That would be quicker than changing a tube, though less reliable.

With can held upright?
Followed the instructions to the letter...

I did think that, but then again it looks like a very handy product to have for racing if you've no support.

I have thought about that as it would be much faster. I should really try it out and see what it's like.
