- Designed to tame the most technical trails, the Grappler’s generously spaced center tread digs into the chunder as well as distributes knob pressure evenly across the tire patch for ultimate grip on even the steepest slabs. The intermediate knob generates a smooth transition into the hard biting side knobs. Accordion sipes allow for the side knobs to find their home in uneven, rough terrain - Tall knobs, strategically siped for maximum bite in the roughest conditions. Generous spacing keeps the tread from trapping mud, while transitional knobs keep traction consistent and predictable in corners - Available in Downhill or Enduro casings.
