The IRC Boken Doublecross TLR tire aims to bridge the gap between CX race tires and Gravel/Adventure tires. IRC engineers optimized the tread pattern for each size tire ensuring the best riding characteristics for a given purpose. Larger volume tires receive a fast rolling center tread for gravel and adventure riding while the 33mm version gives riders the bite needed for CX racing and hard cornering. Burly side knobs add some character to the Boken Doublecross tire for outstanding performance in loose, rough, and loamy terrain  


  • Fast-rolling center tread for gravel and adventure riding paired with burly side knobs
  • For superior performance on loose, rough or loamy terrain
  • Tubeless ready casing provides a lighter overall weight with lower rolling resistance
  • Double layer of sidewall protection
  • High-Grip compound provides incredible cornering traction
  • 60 TPI casing
