An excellent choice for unpredictable roads and trails, the Raddler TCS Light/Fast Rolling tire combines the supple traction of a high-volume gravel tire with the rolling efficiency of short-knobs.


  • Dual DNA compound mixes a low-profile centerline of firmer rubber for faster rolling and increased durability with softer, slower-rebounding side knobs for control and grip
  • Semi-slick design cuts down rolling resistance while still providing ample bite for out-of-the-saddle pedaling
  • Slightly taller overall knob height compared to the original Riddler increases tire lifespan and provides cornering confidence without reducing rolling efficiency
  • TCS (Tubeless Compatible System) is the WTB-designed standardized tubeless rim/tire system designed to meet international ETRTO standards and ensure reliable performance
  • TCS Light/Fast Rolling casing is supple, gram-conscious and designed to be compliant while still trail worthy; single 60 tpi ply saves weight
  • Conditions: dirt, loose, rocky, wet
  • Note: Tire images shown may not reflect size/color/material options available on this page
