Challenge Gravel Grinder Pro Tire 700x33

The Challenge Gravel Grinder Pro Tire is ideal for hardpack, gravel, sand, loose, and rocky terrains.

Intended for all around or dirt/gravel roads, this tire comes equipped with a file tread center and a knobbier shoulder tread. The file tread center pattern offers low rolling resistance on smoother terrain and increased grip when the road gets rough. The shoulder tread is more aggressive for corner confidence and additional control.

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. The Tubeless Tubular version, with 260TPI SuperPoly casing, offers a unique combination of tubeless and tubular construction that is more secure on the rim and more comfortable at lower air pressures, is fast-rolling, and is compatible with both tubeless sealants and tubeless tire plugs.

Features:

  • Handmade tires combine many attributes to create the most comfortable and low rolling resistance tires.
  • Tubeless Tubular system maintains all the performance benefits of the best handmade tubulars. A latex liner is fused to the casing, replacing the traditional inner tube, allowing for the use of a plug to finish a ride or race in case of a puncture too large for the sealant to fix.
  • Includes PPS2, a combination of the sub-tread Puncture Protection System and an additional layer inside the casing to increase resistance to punctures.
  • The Puncture Protection Strip (PPS) is a special fabric placed between a tire's tread and casing to increase resistance to punctures. Designed for rough roads and gravel, PPS2 tires have an additional protection layer between the casing and the inner tube.
  • The Presta valve includes a removable core.
