An all-out gravel destroyer, the WTB Nano 40 tire boasts a high-volume 40 mm casing to smooth out the rough stuff and a Flying-V knob pattern that glides over hard terrain and dig into loose surfaces.

  • Features

    • High-volume 40 mm casing smooths out jarring gravel while also reducing drag and rolling resistance
    • Flying-V knob pattern channels speed from one knob to the next with as little energy loss as possible
    • Nearly uninterrupted centerline provides swift efficiency, while the staggered outer knobs allow you to stay on the gas up chunky climbs and through loose gravel corners
    • The height of the knobs provides traction by digging in while pedaling or braking on loose surfaces
    • Ideal for hardpack, dirt and gravel conditions
