Challenge
Gravel Grinder Pro TLR Tire

Your Gravel Grinding Companion

Challenge Gravel Grinder Pro TLR 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.

It also includes PPS2, a combination of Challenge's sub-tread Puncture Protection System, and an additional layer inside the casing to increase resistance to punctures.

Features

• Casing: SuperPoly Corazza Armor
• Bead Type: Aramid
• Protection: PPS2
• Tubeless-Ready
• 260 Threads Per Inch
