WTB Riddler TCS Light Fast Rolling Tire – 700 × 37 | Tubeless Ready

The WTB Riddler TCS Light Fast Rolling 700 × 37 is a fast, versatile gravel tire designed for riders who want efficient rolling with confident cornering across dry-to-damp and hardpack-to-sandy conditions.

The tread combines a densely packed, low-profile center section for speed with large, supported, toothy side knobsthat provide reliable grip when leaning the bike into corners. This balance allows the Riddler to roll quickly on straight sections while remaining predictable and stable through turns.

Built with WTB’s Light casing, the tire keeps rotational weight low while still conforming to trail features for improved comfort and control. Grip and durability are handled by WTB’s Dual DNA rubber compound, pairing a firm, long-wearing center tread with softer side knobs to enhance traction without sacrificing efficiency.

The Riddler uses WTB’s proven TCS Tubeless Compatible System, featuring an improved bead shape for secure tubeless setup, lower pressures, and increased comfort and flat resistance.
