The Surly Dirt Wizards are highly focused – one might even say spellbound – on providing traction and control on the kinds of surfaces where nary traction nor control are to be found.
Features
- Its tread is composed of a dual row of aggressive, trail-gobbling, beveled knobs in the center and well-spaced, siped knobs to dig into loose corners.
- Designed to work on 50mm rims, Dirt Wizards are tall and wide, providing next-level traction and cushioning.
- The casings are flexible and responsive, yet durable and supportive.
- Minimum rim size for these naughty little wizards is a 35mm outer rim width.
