Challenge Gravel Grinder Pro Handmade Tubeless Tyre Tan 700x33

5 out of 5 Customer Rating

The Details

Make your mark on the gravel scene with the Challenge Gravel Grinder. This tyre combines a fast rolling diamond center with aggressive shoulder knobs that only hook-up when the terrain gets soft, muddy, or a bit sketchy.



Handmade_icon high resThe Hand Made Tubeless Ready (HTLR) is molded flat, not in a horseshoe like a Vulcanised (V)-TLR or V-CL. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance. A normal vulcanized tubeless tire is molded in a U-shape to make the sidewalls rigid so the system does not “burp” or lose air when it deforms after it encounters a surface imperfection.

Pps-high-resThe new Challenge H-TLR is anything but normal. Where V-TLR is stiff, high rolling resistance and uncomfortable to ride, the new H-TLR maintains the soft supple qualities of all Challenge Handmade tires but sets up with a sealant on TLR wheels.A bead-to-bead inner coating gives added puncture protection to these new H-TLR tires and greatly reduces any air pressure dissipation. Enhanced longevity has been gained with the addition of an aramid bead protection strip, to reduce rim chafing.

Features:

  • Air retention & Puncture Protection coating
  • Bead Protection Strip & Seating Line (CHAFER)
  • Improved side protection casing for better cut resistance (PROTECTION SHIELD)
  • High TPI and Supple casing
  • Lower tire pressure than standard TLR
