K2 Mindbender 89Ti Men’s Skis. When soft snow is in short supply, turn to the Mindbender 89Ti. Although it’s built with the same Titanal Y-Beam construction and All-Terrain Rocker profile as its other metal-reinforced Mindbender siblings, the 89Ti stands apart thanks to a narrower waist width. Resulting in a ski that has the precision edge hold you need to dominate the hardpack but is still wide enough for forays into the ungroomed. Skis with All-Terrain rocker have a gradual rise to the tip for great versatility in all conditions, with a short, low rise in the tail for added control variable snow. A single wood species ensures consistency – giving riders the advantage of a proven flex, durability, and snap. Energetic, tough, dense wood that absorbs impact. Tip Width (mm) : 130. Waist Width (mm) : 89. Tail Width (mm) : 114. Tail Type : Partial Twin.
