K2 Mindbender 89Ti W Women’s All-Mountain Skis. The Mindbender 89Ti W is an all-mountain freeride ski with a carving pedigree. Outfitted with classic construction and a powerful twist thanks to Titanal Y-Beam technology, the 89Ti provides precise, predictable, smooth turn initiation, and enhanced power transfer. These 89Ti’s are optimized for the fluid hardpack experience, with confidence-inspiring stability and a high-speed edge hold. The All-Terrain Rocker profile gives you freedom in its stability and planted experience to explore off the beaten path. The Mindbender 89Ti W is the perfect dynamic companion for when you’re in the mood to rip but soft snow isn’t on the menu. All-Terrain Rocker: Gradual rise in the tip with a short, low section in the tail for greater versatility in all conditions. Titanal Y-Beam Construction: Titanal has long been used in high-end skis and is known for providing a damp, stable ride at high speeds and on variable terrain, but K2’s Y-Beam technology takes things a step further with dramatically enhanced performance tuning. Y-shaped prongs set over the edges in the shovel of the ski provide precise, powerful turn initiation, while the narrower metal shape in the tail of the ski provides the support you need for charging while still remaining maneuverable, forgiving, and easy to break free from turns. Correct Flex: Eliminates the overly stiff mid-section typically found on shorter length skis. K2 addresses this with an insert that leaves a smooth, consistent flex profile optimized on every size from longest to shortest. Aspen Veneer: Lightweight and resilient, aspen is a great all-around core material. Range : 170 to 179. Waist Width (mm) : 89. Tip Width (mm) : 130. Tail Width (mm) : 114. Tail Type : Partial Twin.
