Thought this sounded pretty cool/interesting idea: http://enduro-mtb.com/en/schwalbe-introduces-dual-chamber-tires-for-ultra-low-pressures/
wonder how expensive this is gonna be?

The combination of two different pressures creates a certain kind of a progressive resistance when the tire is compressed
Hopefully they were also designed "with traction in mind.".....which is completely unlike, you know, normal tires
Was going to post exactly that......which is completely unlike, you know, normal tires
so i guess there will have to be a valve attached to the outer chamber (basically just like a standard tube) that goes through the inner chamber and through the rim? assuming that valve needs to be air tight against the rim how will that not effect tire compression at that specific point?Of course youll need a rim with holes for two valves.
The concept sounds similar to the Tubliss system for moto. 100-110 psi in the inner (red) tube to act as a beadlock and rim protection, and 0-10 psi in the outer chamber for tractions:
All the weekend warrior bankers who buy schwalbe tires need something new to buy.So what 'problem' is this supposed to be solving?
It's probably not a rigid steal valve in the traditional sense, I'd assume the space between the rim interface and the inner chamber is probably flexible.so i guess there will have to be a valve attached to the outer chamber (basically just like a standard tube) that goes through the inner chamber and through the rim? assuming that valve needs to be air tight against the rim how will that not effect tire compression at that specific point?

Likely this is going to be a tube'd setup, which is fine by me. Tubeless sucks it on both ends IMO.It's probably not a rigid steal valve in the traditional sense, I'd assume the space between the rim interface and the inner chamber is probably flexible.
Maybe you missed it in the article: "Each tire is split into two sections, both need no tube."Likely this is going to be a tube'd setup, which is fine by me. Tubeless sucks it on both ends IMO.
You aren't ready for these tires.Likely this is going to be a tube'd setup, which is fine by me. Tubeless sucks it on both ends IMO.
Have you tried the Super Gravity or Michelin Reinforced tires? The sidewalls are quite a bit thicker then EXO or Snakeskin.All the weekend warrior bankers who buy schwalbe tires need something new to buy.
On an equally serious note (which is fully serious) I do wish there was something tougher than current 1.5 ply tires run tubeless. This probably won't fix that unless they can then use lighter casings because the design is a more complicated balloon that doesn't pop like regular tires do.
Tubes hold air. Tires use tubes. Tubes will be used if I fit these to my W35 w/ Pro 2 EVO's I have ready to build.Maybe you missed it in the article: "Each tire is split into two sections, both need no tube."
Under boob... through a blouse?No way! Under -boob ALLday.
I think you are unclear as to what is happening here.Tubes hold air. Tires use tubes. Tubes will be used if I fit these to my W35 w/ Pro 2 EVO's I have ready to build.
Dammit still a 'Chimp'
another new wheel standard? or everybody is gonna make another new hole on the rims?
Not really - I'd gone and panned focus on comments from many sources on the interweb, it's basically a formed and swedged tube for the inner, and I am not a fan of Tubeless systems. Some tires can be removed by hand and installed by hand and there is no way I am running just that going downhill.I think you are unclear as to what is happening here.
Dude, Google underboob.Itll change your lifeUnder boob... through a blouse?
Whatever.
UPDATE: Schwalbes PR man just rang back with a bit more info: Basically theres an inner tube, but its not really a tube, its a new construction process. You can pump up to 60psi into the interior chamber and as low as 12psi on the outside, though its a bit squirmy that low. Essentially, its a second chamber that uses that high pressure to provide the above mentioned security benefits by pressing the standard tires bead harder into the rims hook, but only takes up about half the total volume. They cant say more than that until the patents are final. In the meantime, check out Nuetechs similar (but Schwalbe says different) system for motorcycle tires to get a visual.
Mmmm progressive resistance.a certain kind of a progressive resistance
Just out of curiosity: how many flats do people get running tubeless? Is there really a problem that needs to be solved?Sounds pretty cool actually - I'd be keen to give it a go. Flats suck, and anything that allows for good traction while preventing pinches and rim damage is a good thing IMO.
