Challenge Gravine Pro TLR

Taking from their knowledge of cyclocross, Challenge Tires combined a fast-rolling center for speed, with slightly increased knob height in comparison to their other gravel tires, for enhanced grip through muddy sections and over rocky terrain, with improved mud/dirt shedding. the Gravine is a more aggressive, versatile, and dependable tire on multiple terrain types in differing conditions.
