The K2 Pinnacle 105 Ti is an aggressive assailant that should make any mountain tremble to its core. It utilizes a combination of burly fir wood with a metal laminate to achieve red line speeds each and every time down the mountain. K2 then employs a low-density composite core running from the extremities through the core to reduce swing weight and ensure the Pinnacle maneuvers like a hummingbird. “This ski is like a Swiss Army knife, it does it all really well,” said tester Adrian Bouthot. “It’s such a powerful ski in and out of the turn,” described Mo Mitchell. Rounding out our testers’ thoughts, Mike Filander called it a, “Jack of all trades and a master of many. Absolutely love its combination of playfulness and carving abilities.”
