Airless tyres -

[Deleted]

Vid by www.energyreturnwheel.com , imagine how heavy the wheels would get on the Clwyds with mud getting into the tyres, obviously just for show and the end product would surely look like a normal tyre with sidewalls.

Interesting though.

Great idea ...Might gather enough mud + gravel to stop Gus and Ben from riding the steepest climbs and join the rest of us pushing ;D

The finished product would be worth a second look though.
