Challenge Tires Gravel Grinder Pro Handmade Clincher

Make your mark on the gravel scene with the Gravel Grinder. This tire combines a fast-rolling diamond center with aggressive shoulder knobs that only hook-up when the terrain gets soft, muddy, or a bit sketchy. This handmade clincher combines a supple, 260TPI SuperPoly casing with natural rubber tread for long-distance comfort, confident cornering, and quick handing. This tire includes PPS2, a combination of our sub-tread Puncture Protection System and an additional layer inside the casing to increase resistance to punctures.

Handmade
- Handmade tires combine many attributes to create the most comfortable and lowest rolling resistance tires.

PPS2
- The Puncture Protection Strip is a special fabric placed between a tire's tread and casing to increase resistance to punctures. Some tires designed for rough roads use and gravel have an additional protection layer between the casing and the inner tube.
