Challenge Gravine Pro 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, the Gravine is designed to push the boundaries of gravel further, allowing for totally new adventures. Taking inspiration from the knowledge of cyclocross, the height of the knobs has been increased in comparison to our other gravel tyres, for enhanced grip through muddy sections and over rocky terrain, as well as featuring an open-tread design for improved mud/dirt shedding. Combined with a fast-rolling centre-line for speed, the Gravine is a more aggressive, versatile, and dependable ride on multiple terrains, in differing 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.
