Challenge Gravine XP 28'' tyre

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.

Technologies

Challenge Handmade

Handmade tires combine many attributes to create the most comfortable and low rolling resistance tires. Handmade Clincher tires perform better than any vulcanized tubeless system! The HTLR is molded flat. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance.

PPS

The Puncture Protection Strip is a special fabric placed between a tire's tread and casing to increase resistance to punctures. Some tires deisgned for rough roads use and gravel have an additional protection layer between the casing and the inner tube.
