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. The Tubeless Tubular version, with 260TPI SuperPoly casing, offers a unique combination of tubeless and tubular construction that's 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. This tire includes PPS2, a combination of our sub-tread Puncture Protection System and an additional layer inside the casing to increase resistance to punctures. The Presta valve includes a removable core.
Handmade
- Handmade tires combine many attributes to create the most comfortable and low rolling resistance tires.
Tubeless Tubular
- 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.
PPS 2
- The Puncture Protection Strip 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.
