It works.
I did something similar with a double tube setup a while back. The innermost tube wrapped in Kevlar.
It was just too much trouble to make the double tubes, so I scrapped it, but if Schwalbe makes it easy to deal with, it's a great idea.

NASCAR does a tire-within-a-tire thing for safety. If the outer tire gets cut, the inner will still let you retain some control.

The tube within a tube thing would be great for preventing rim damage and pinch flats. It's worth noting that it only works if the inner tube has some sort of non-stretchy casing. You can't just put a typical tube inside a tubeless tire.

Cool implementation for motorcycles. http://www.motorcycle-superstore.com/57 ... 7AodYwYADQ

So how do we make this a DYI thing?
Ideas.. Anyone?
Could you wrap a tube in gorilla tape to prevent it from expanding? With the tube in hand, fill it to take shape, then wrap it in gorilla tape completely. Drill and valve your tubeless hole in the rim, install tire and tube normally and inflate. Thoughts?
What could possibly go wrong? ;)

How about using a road tubular tire as the inner tube?

The simple way: Sew a tube in the desired size of a pair of jeans around a tube, inflate it and paint it with latex. Run tubeless for the main chamber.
The way I did it back in the day: Sew a tube of Kevlar, and do the same, and put it inside a bigger tube.

I think I'll go with tape, me and sewing don't get along.

Tape probably won't work for long if at all.
You can also just lay up the fabric on the tube inflated to the size you need, and fixate it with liquid latex.
Probably the best solution not that I come to think of it.

Hi, I'm new here and found my way here looking for DIY tubeless sealant.
Anyway, I've thought of dual chambered mtb tyres long before schwalbe went public with theirs.
A friend of mine uses dual chambered tyres on his motocross bike. Apparently they've been round forever.
I was looking at using a 24" tube and wrapping it in tape as mentioned above. I did a trial run, type of thing. Pump up the tube somewhat. Then evenly wrap it with tape. I used electricians tape. The issue I couldn't get over, was how would I inflate the tyre chamber? It would require a hole through the tube with an extra long valve stem. I cut a hole through the tube to pass the stem through, but I couldn't get it to seal.

I wonder if Schwalbe will supplying the individual parts.

Drill a second hole in the rim fit a road tubular tyre and use the Schwalbe part to add air to the low pressure chamber.

I want this for my DH bike but I have never had an issue with low PSI in my tubeless setup.
