Cannonball is a go-to gravel race tire for normal conditions. The tread pattern features a directional, tight-knit center tread that sheds dirt and debris to decrease rolling resistance, and side knobs for effective cornering traction. Cannonball is built for all-around gravel riders and racers. How It Works Center lugs are raised and ramped for rolling efficiency; the diamond-shaped lugs squeeze in for grip as they contact dirt, then back out to shed debris Transitions lugs are spaced out and vary in height to boost traction L-shaped side lugs dig in for grip while braking through corners, but roll quickly when off the brakes Tire Diameter: 650bLabeled Size: 650b x 47Rim Diameter: 650bWeight: 525Tire Type: Tubeless ReadyTPI: 60Tire Bead: Folding
