A Race-Ready Choice For Mixed Terrain

Featuring a tread design for maximum speed and control across varied surfaces, total protection from punctures and sidewall abrasions, and a supple 170 TPI casing, the CADEX AR Tubeless Gravel tire offers speed, durability and compliance in any situation.

Compact diamond-shaped knobs on the centerline tread and trapezoidal knobs on the outer edge, combined with exclusive AR-S dual compound rubber, make the CADEX AR Tubeless fast on pavement and confident on gravel and dirt.

Super-supple 170 TPI casing offers a smooth, compliant ride quality and helps minimize fatigue during long-distance, multi-surface races or rides.

Dual Shield bead-to-bead puncture protection combines a proven Race Shield+ layer on the center of the tire with all-new X-Shield on the sidewall. The result is proven protection from road debris, sharp rocks and harsh abrasions.


  • Compact diamond-shaped centerline knobs for maximum speed on smoother surfaces without sacrificing handling under rougher conditions.
  • Intermediate hexagonal knobs deliver a seamless transition from the centerline, and taller outer trapezoidal knobs provide traction in the corners.
  • AR-S dual compound tread technology for total efficiency, durability and grip.
  • Dual Shield puncture protection combines Race Shield+ and X-Shield for outstanding bead-to-bead tread and sidewall protection.
  • Lightweight 170 TPI casing gives a smooth, supple ride quality.
