https://www.renehersecycles.com/700x44-corkscrew-climb-a-new-type-of-tire/Yet they filed for a patent!
Of course, I just keep a pair of worn knobby tyres that have become slick in the center section. I rode them yesterday. 102km with 36km on gravel roads.
Is this really new?
I don't think so. Maybe new to them.
