OUTSTANDING GRIP AND TRACTION - Knob distribution and geometry are designed to offer outstanding grip and traction with high resistance in both dry and wet conditions, and from soft/loose to hard terrains. WIDE RANGE OF TERRAINS - The tread compound is resistant to tearing and cutting, and suited to a wide range of terrains – from soft and intermediate to rocky conditions; the carcass of EF-07 is stiffer than with the green stripe version.
