Designed for improved performance and traction across muddy sections and on more rugged, rocky terrains, the Gravine is designed to deliver. Featuring a more aggressive tread pattern, this tire pushes the boundaries of gravel further, allowing for totally new adventures.
With the growing demand for more robust Gravel tires, Challenge has developed a new technology applied to the handmade construction, adding Xtra Protection (XP) for more endurance rides on rougher terrains. The Gravine XP is designed to take you places others can't. Starting with CORAZZA ARMOR SILVER for enhanced sidewall protection, the Gravine XP also includes CORAZZA ARMOR GOLD , a special layer of a tightly woven material placed on the tire, reinforcing it further for more aggressive conditions.
