K2 Pinnacle 105 ski review, 2017/2018 men's Big Mountain Category, from our equipment experts at Realskiers.com powered by Masterfit.

The story behind the revision of K2’s Pinnacle 105 is a tale of error correction, optimization and resurrection. The first generation Pinnacle 105 was on the soft side, super easy to steer but showed its frailty at speed. For 2018, K2 powered up the Pinnacle 105 by increasing the Titanal dosage over the edge by 20 percent and pumping up the camber underfoot. The resulting stability significantly improves both calm on edge and responsiveness. It’s amazing what a little more mass will do: K2's new Pinnacle 105 now behaves more like a Power ski than a docile cruiser, although it hasn’t lost touch with the Finesse side of its personality. The Pinnacle 105 is one of the few Big Mountain skis that feel narrower than they measure with a little extra kick through the turn transition. K2's improvement in hard-snow grip, while notable, hasn’t changed the Pinnacle’s predilection for soft snow. The ski is still amply rockered with a tapered tip and tail—all traits geared to off-trail conditions. In Erik Korman's opinion: “Excellent new version. A one-ski quiver contestant!”
