Riding in the Cascade Mountains, the folks at Rene Herse discovered the joys of gravel riding. They soon realized that their narrow racing tires were reaching their limits on rough surfaces and started dreaming of wide and supple high-performance tires that would float over the gravel, rather than grind through it.
When they started riding on gravel, they wondered: Would it be possible to combine the speed of racing tires with the go-anywhere ability of wide tires? Testing on real roads, they found that wide tires could be as fast as narrow ones, and that high pressures weren’t needed for optimum performance. That was the start of the “All-Road Bike Revolution.”
