The Grappler is where the All-Terrain fell short, it's meant for the roughest and most technical trails - just like that gnarly stuff you see Remy Metailler hitting regularly. With smaller center line blocks and mid-transition lugs gives you are more stable and consistent cornering and braking through trecherous terrain - loose dry or slick mud. Reinforced and modified lug profiles will support extreme lean angles for positive cornering at all angles.
