There are routes covered with jagged flint rock, where the wind is unforgiving, and the destination is far beyond the horizon. For the toughest days of gravel, when winning looks like finishing, we created the Cannonball.

We designed the 38c Cannonball to be a first-choice gravel racing tire — Dirty Kanza, Trans Iowa, Land Run… it’s conquered them all. The directional, tight-knit center tread efficiently decreases rolling resistance while the side knobs increase cornering traction. The center tread’s diamond pattern is optimized specifically for gravel riding and sheds dirt and gravel debris.

When extra puncture protection isn’t necessary, our Light and Supple casing offers decreased weight and a comfortable, ultra-supple ride quality at lower pressures when set up tubeless.
