With its 84-mm waist, the 2017 Dynastar Powertrack 84 is a shade quicker than the top-of-the-line Powertrack 89. It’s also a bit lighter and livelier, lacking the metal reinforcement of the 89. The 84 is similarly built for all-mountain, all-conditions versatility, blending hard-snow carvability with soft-snow smeariness-just lighter, softer-flexing and a bit more forgiving than the 89. And like the 89, it’s sold either flat (no binding) or as a system, with the same 12-DIN Look SPX Dual binding, which accepts either a conventional alpine-norm boot sole or the newer rockered WTR-style style boot sole.
Dynastar’s All Mountain collection of versatile mid-fat generalists includes four Powertracks with waist widths 89, 84 and 79 mm and target ability levels ranging from expert down to intermediate. The Powertracks, which return unchanged for 2017, blend some of the hard-snow carvability of Dynastar’s Speed Zone series with some of the smeary looseness and soft-snow buoyancy of the freeriding Cham series. There’s classic camber underfoot, for arcing on groomed snow. And there’s rocker tip and tail for shock absorption and flotation in powder and crud. Meanwhile, Dynastar’s Five-Point Sidecut gives the Powertracks a dose of newschool, freeridey slashiness: The tip and tail are tapered (ie, the widest points are closer to the foot), making them looser in the snow, easier to pivot and foot-steer. All Powertracks are built on durable, responsive poplar wood cores. The top two models (89 and 84) are laminate constructions with full-length, full-height, vertical sidewalls, for maximum edge power and torsional rigidity (twist resistance). The two 79-mm models (79 CA Fluid and 79 CA Xpress) have vertical sidewalls underfoot that taper down into softer-flexing, more forgiving cap construction fore and aft, for intermediate-friendly mellowness at slower speeds. The top two models are sold either flat or with binding; the lower two are sold only as ski-and-binding system.
