A bigger change than 29: dual chamber suspension?

[PurpleFrog]

I think this picture explains the concept:

...You can have extremely low outer pressure for a huge contact patch and higher inner pressure to avoid pinch flats.

Ride reports are extremely promising:

How this will interact with wheel size is hard to say. But it might put a premium on agility while making the 29er rollover advantage unnoticeable, therefore driving a return to 26 wheels - which would be hilarious. Otoh, it might not even be sold in 26 in today's market!

Re:

Sounds like tthe best of both worlds, has to be easier than tubeless surely?
Will probably come at a price though....

I don't get why you are shocked: $200 seems to be the cost for upgrading both wheels. For what may be the biggest upgrade in bike handling since decent suspension forks, that seems quite cheap - I was expecting the system to require special rims for $250 a pop.

And that's an discounted entry price. My Schwalbe Almotions are supposed to be £45 a tyre, but by shopping around I got them for £25 from Germany, and next year that will probably the standard UK price.

Re:

They just need to fit Bluetooth pressure monitors to them now.
Did Michelin try something like this or Panaracer a year or so back.I remember reading something with a similar dual chamber when looking for tyres, but didn't actually look to see what it was.

i did like running beefy tyres at low psi
but i picked up quite a few flats an ended up going back to higher psi

so if this does what it says it does then id give it a go
an there welcome to send me some betas to test
