Washburn
Teravail Cannonball (40mm and 47mm): https://www.teravail.com/product/teravail-cannonball-tire-394759-1.htm
Gravel race tire; 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.
