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 Cannonball to accommodate modern gravel rigs whether you’re racing Dirty Kanza, Trans Iowa, or Mid-South… 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. - Light and Supple—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. - Durable Sidewall—This construction consists of a robust woven nylon composite reinforcement between the outer rubber and the inner casing within the tire’s sidewalls to prevent tearing and abrasions.

When you're out on a ride the last thing you want is to be limited by your tires in any way. Surly's ExtraTerrestrial tires were designed to let you ride without limits by following a simple tenet for tire design: make 'em high-volume and kick-ass. The ExtraTerrestrial tire was meant to serve as a heavy-duty off road touring tire that shines on hard pack surfaces. It uses a nylon breaker in the sidewalls for cut protection, a molded pattern for anti-cut propagation, and a Kevlar cap under the tread to protect against flats. The ET tire uses a distinctly directional tread pattern and its width yields more traction than you might expect from a tire with such little rolling resistance. The tread is low profile with a file tread in between blocks. The ExtraTerrestrial tire has enough width and traction for the soft stuff and won't bog you down on smooth or hard surfaces. It's made to be durable and versatile and is at home on tour or on the trail. - Bead Seat Diameter: 559mm - Casing: 60tpi, tubeless-ready bead (928g)
