Details

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, fast rolling, and compatible with both tubeless sealants and tubeless tire plugs. This tire includes PPS Ganzo + PPS2, a lightweight and supple Puncture Protection System, and a high mileage, grippy, natural SMARTplus tread compound. The Presta valve includes a removable core.

Tubeless technology

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.

Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.

UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
