Challenge Gravel Grinder Race Tire

The Gravel Grinder Race is the optimal tire for endurance events that eschew pavement for dirt and gravel roads. Think Dirty Kanza or the Almanzo racing series. These events put a premium on efficiency, grip, durability, and minimal maintenance. This tire was developed with these criteria at heart. With a 38mm width profile, coarse file tread center, and perfectly aggressive shoulder knobs, this true clincher tire carries speed, handles the uneven surface, and corners with confidence in all conditions.

Protection comes from the durable vulcanized rubber construction and nylon casing that offers a still supple 120tpi thread count. Challenge has utilized two layers of aramid fabric in the casing, designated as their PPS2, or Double Puncture Protection System. Durability and ride-ability is the alchemic mixture tire manufacturers balance depending on specialization. With the center tread pattern you will cruise comfortably on pavement, and employ the width and edge knobs for flotation and traction on gravel or hardpack. Commuters and freeroad enthusiasts who tackle mixed use conditions on trails, bike paths or rough urban roads will also love this tire.
