Challenge Gravel Grinder Pro Handmade TLR 700c x 40mm

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.

Challenge H-TLR tires meet the new ETRTO and ISO standard and are hookless compatible.

Handmade TLR are best combined with the Challenge’s SMART Tubeless SEALANT, which protects the natural properties of its components for a longer-lasting performing tire, while further enhancing puncture protection and air tightness.
