The 2017 K2 Pinnacle 105 (sidecut radius: 19 meters) is an all-mountain soft-snow specialist designed to be a versatile everyday ride in locales where snow tends to be soft and abundant. It's narrower and edgier than the flagship Pinnacle 118, with metal reinforcement over the edges that the 118 doesn't have, for enhanced performance on hardpack. And where the core of the 118 is all wood, the 105 is a mix of wood over the edges (strategically placed, like the metal, to bolster edge power and solidity) with K2's Nanolite foam down the middle to keep things light overall. K2's Freeride series grows to four models in 2017 with the addition of a new model, the Pinnacle 88. The 88 becomes the narrowest Pinnacle, "bridging the gap," K2 says, "between the Freeride and All-Mountain collections." The other three models-Pinnacle 118, Pinnacle 105, and Pinnacle 95-return unchanged, right down to the graphic. All have flat tails and are built for edgy, traditional, "directional" performance in soft snow (as opposed to the looser, surfier, more new-school performance of the twin-tip models in K2's Freestyle collection). All Pinnacles feature K2's Konic technology, which amounts to perimeter weighting for skis. Mass is concentrated over the edges (using denser core woods and in some models metal reinforcement), with lighter materials down the middle. That's designed to supply powerful edge grip while keeping the overall construction light and lively. All models are tapered tip and tail (the widest parts of the ski are moved closer to the foot) to promote a loose, smeary feel in soft snow and powder. That promotes easy speed control and last-second direction changes. All Pinnacle models are Hybritech constructions, with grippy, powerful sidewalls underfoot combined with forgiving, soft-flexing cap construction tip and tail. And all are torsion-box constructions, with their cores wrapped in a sheath of tri-directional fiberglass tuned for optimal torsional rigidity (twist resistance). All Pinnacle models are sold flat. K2 was founded in 1962 by the Kirschner brothers, who pioneered the use of fiberglass in ski construction at their Vashon Island, Wash., factory. The brand is now based in Seattle and builds its skis in China. It is owned by Newell Brands, a consumer products conglomerate. -J.C.
