Spark R&D built the Surge Splitboard Binding for big days, big lines, and big mountains in the backcountry. Its Rip 'N' Flip highback is Spark's most robust highback to provide the stiffest feel for greater control in demanding terrain, and the baseplate is a single piece of CNC-machined aluminum for a solid performance that won't get flimsy overtime. The Pillow Line straps also have a solid, one-piece construction for durable longevity, and their all-around support lets you use the toe strap as a toe cap or a standard strap. Not just stiff, the Surge is a fully featured binding to make the ascent and descent as easy as possible. The highback has a tool-free forward lean adjuster that you can customize in ride mode and touring mode for easier hiking.
