WTB Raddler TCS Light Fast Rolling Tire – 700 × 40 | Tubeless Ready

The WTB Raddler TCS Light Fast Rolling 700 × 40 is a gravel and cyclocross tire designed for dirt, gravel, and loose terrain, offering a balance of efficiency, durability, and confident cornering.

Compared to the original Riddler, the Raddler features slightly taller center and intermediate knobs, increasing tread life while maintaining similar rolling efficiency. This makes it well suited for riders who want a fast gravel tire that holds up better over extended use or rougher conditions.

Tall, toothy outer lugs provide dependable cornering traction, helping maintain control on fast gravel descents and loose turns. Grip and efficiency are managed by WTB’s Dual DNA rubber compound, combining a firm, long-wearing center tread with softer side knobs for predictable handling.

The Light casing reduces rotational weight while still conforming to trail irregularities for comfort and stability. Built with WTB’s TCS Tubeless Compatible System, the Raddler offers reliable bead retention, straightforward tubeless setup, and the ability to run lower pressures for improved traction and ride quality.
