GRUS

Inspired by the sand and gravel fragments that cover most gravel racing courses, the American Classic Grus is designed to give athletes the edge they need to charge over any terrain. Its tightly-spaced central tread delivers higher rolling speeds on straight sections, while the aggressive, hooked shoulder knobs provide lateral control in high-speed cornering and improve grip on rough terrain. Plus, open transition knobs prevent mud and sand build-up. With a Tubeless Ready 120 TPI casing, abrasion and cut-resistant Stage 5S Armor, and American Classic's Rubberforce G tread compounds, the Grus is ready to face a wide range of conditions at racing speeds. Don't let challenging terrain slow you down - upgrade to the American Classic Grus and experience the ultimate in speed, control, and performance.

HOOKLESS COMPATIBILITY

Some American Classic tires are compatible with hookless (Tubeless Straight-Side/TSS) rims. To be compatible, the following must be met:

  • The tire must be a Tubeless-Ready model,
  • The tire must not include Stage 3 Flat Protection or Stage 3S Flat Protection,
  • The tire must be placed on an appropriate width rim, 
  • The rim must meet current E.T.R.T.O. standards for tubeless systems, and
  • The air pressure must be below the lowest maximum pressure as listed by both the rim and the ISO recommended pressure for Tubeless-Ready tires on hookless rims.  

More information on hookless compatibility can be found on our Tire and Rim Compatibility page.

  • Lamplighter (all versions)
