Have we done these yet? Couldn't find anything..
Look pretty interesting from an engineering point of view, and will take up much less space as an emergency tube than a standard one. Even tempted to use them on the SS hack if they're as durable as they claim - at the price you'd want them to be though!

The heaviest thing after the water in my long distance pack at the weekend was two 29er tubes, so this is of interest.
Ditto, very interested if I can reduce the weight and bulk in my pack.
Looks like you can buy them here: https://www.bike-components.de/en/tubolito/
Not cheap though. I do get the occasional unplugable tubeless split, so the emergency tube does get some use. The standard ultralight ones aren't too far off this, and whilst not at all durable, are ok as a tubeless spare.
I'd have thought they would be of much more interest to roadies to save weight at the wheel. Most MTBers who are serious enough to use tubes that expensive would be on tubeless, they'll not sell many as emergency run-flats.
Wonder if they won't handle high pressures for some reason.
Gives me horrible memories of Panaracer green polyurethane tubes. Hope these are better for the sake of anyone who buys them
I wonder how stretchy they are? I carry a 27.5 tube which is good enough as an emergency for 26, 27.5 and 29" wheels.
Aaaaargh.. 30 € - I'm out!
