Commercially available sprung tyres/wheels? I was wondering if anyone knew of any commercially available sprung tyres or wheels. I'm talking about wheels that take do the shock absorption instead of a pneumatic tyre.

This is all I can find at the moment



I'm sure I saw a kickstarter for a set a while ago but I can't seem to find it anywhere.
Loopwheels makes bicycle wheels with springs in stead of spokes. They also had a successful Kickstarter, so it might be what you were thinking about. They do however still rely on normal tyres and rims, so can't be said to work without pneumatic tyres. Although I bet you can run a pretty high tyre preassure quite comfortably with these wheels.
