Challenge Gravel Grinder Pro

• 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.
  
• Includes PPS2, a combination of our sub-tread Puncture Protection System and an additional layer inside the casing to increase resistance to punctures.
