Can not be used with rim brakes. This might be the a great back-up tube for those of us that ride tubeless, much less weight!

Definitely interesting.
But 20 euros!
Wonder how the durability compares against latex and butyl, particularly tear and abrasion resistance.

Will totally use this as a back-up tube on my tubeless mountain bike, and that's where I see the real market for this. Are any racers really still running tubes? Genuine question, I don't see myself ever going back for dirt riding.

I'm going to try and get a couple of these. I heard about them, but thought they only came in the 26" size. Plastic tubes make a lot of sense now that most bikes are moving to disc brakes.

Are these like the FOSS tubes? They seem to be "like" them in theory. I am sure they are wildly different, but the similarity is there from what I am reading. Using a lighter to "patch melt" the tube is kind of cool. Not sure it is as safe as a patch, but if it did work carrying a lighter to fix a flat is a fun idea. Very MacGuyver-like

Only available for mountain bikes?
Didn't realize they were weight weenies.

Maybe the small 29 size would work for a gravel grinder with discs?

Why would a gravel grinder be concerned with saving weight in the tubes?
This would be an interesting tube if it wasn't susceptible to failure from heat.

So... the selling point is weight savings? And not a word on rolling resistance?

I don't get it.

Are these just rebranded Foss tubes? They look extremely similar. Foss makes tubes for all sizes and a pinch flat can be "fixed" with a lighter.

edit: ah, Mr. President beat me to it.

Further investigation shows that the materials between Foss and Schwalbe are different. Schwalbe Evotube use BASF Aerothan as the material, which cannot be used on a bike with rim brakes according to this article (http://www.bikebiz.com/news/read/production-to-start-on-schwalbe-s-thermoplastic-inner-tube/018702).

The Schwalbe tube is also seemingly lighter than the Foss tube. Foss is ~60g for a 700x23-26mm tube, whereas Schwalbe is 76g for a 29er tube.

Excellent point; this really is consideration #1, right?

I don't get it for MTBs. I haven't had a tube in my mountain bike in 10 years.

I can maybe see it for a disc-equipped gravel grinder type bike. But for MTB where tubeless has long been the standard I can't see the benefit of a super expensive tube.

I wonder how durable that valve attachment area is- as a spare it would ban to be folded in my pocket.

Butyl tubes are sometimes known to fail on bike kept inside cars on hot, sunny days. How will these fair in a hot car?
