Superior Performance on Loose, Rough, or Loamy Terrain

IRC Boken Doublecross Gravel Tire has a fast-rolling center tread for gravel and adventure riding paired with burly side knobs.

As its name implies, the Boken Double-cross is a dual-sport tire. It is a CX race tire and aggressive all-conditions gravel tire. The engineers at IRC optimized the read pattern for each size. This 42mm tire has a fast-rolling center tread for gravel and adventure riding paired with burly side knobs that hook up when the gnar gets gnarly.

With more bite than the file-tread Boken, the Boken Double-cross gives you superior performance on loose, rough, or loamy terrain.


  • High-grip "Boken" compound
  • Side blocks hook up in loose corners
  • Closely spaced center tread rolls incredibly fast on hard surfaces
  • Support knobs add grip while helping to float over the soft stuff
  • Reinfornced sidewalls add flat protection and keep the tire from squirming when run at low pressure
  • 700 x 42mm (622x42) ISO
  • Tubeless Ready
  • 60 TPI
