Details The Spark R&D Arc Splitboard Binding is the most popular splitboard binding in the world, and for good reason. The binding is incredibly lightweight, is simple and easy to use, and is super dependable. With a medium flex that lends itself well to the majority of riders out there, the Arc has a slightly surfy feel ideal for riders that prefer a little more mobility. Their ultradurable new Pillow Line Straps are made using a single-piece construction, and are both comfortable and waterproof. The Rip 'N' Flip highback quickly moves from ride mode to tour mode, and the new whammy bars allow you to quickly adjust your climbing wires for the angle of ascent. New for 2021, every piece of this binding (except a few screws and buckles) is made in house at Spark R&D in Bozeman, Montana. Flex Rating (1 = soft, 10 = responsive) 4-6 Highback Rip 'N' Flip Highback With a shape built from 3D scans of popular splitboard boot models and a list of rad features designed specifically for and fully appreciated by the splitboarder, the Arc highback has a moderate amount of glass fiber fill for medium flex and a surfy feel. The tool free forward lean adjuster (FLAD) offers complete customization from 0° to 22° in ride mode. The Forward Lean Adjuster toggles easily between forward lean position and -13° touring position for easy transitions. Straps Pillow Line Straps Arc Pillow Line Straps are lightweight - 46% lighter than their fabric strap predecessors. They are ultradurable, comfortable, waterproof, one-piece molded construction, and made 100% in-house. Strap pillows are thin and flexible for a comfortable, conformed fit, while thicker ribs are held off the boot and provide stiffness for a uniquely responsive ride. Arc ankle straps are smaller around the boot than the Surge and feature a flex window for max agility while maintaining support. The toe straps come in one construction for both Arc and Surge models, and are designed to be used as a toe cap but also fit traditionally over the top. Buckles Ladders and adjusters are produced in-house with unique thermoplastics that maintain flex over a wide temperature range, performing well on spring tours as well as sub-zero suffer fests. All straps incorporate Burton's time-tested bomber buckles. Baseplate CNC Machined Aluminum Shaves weight yet maintains strength and performance. Whammy Bar Climbing Wire A single fatty climbing wire is built into the baseplate with a side arm lever for easy position changes on the steeps. You can switch easily from stowed, to low (12°), to high (18°) and back again while touring. Snap Ramps & Side-Lock Tesla Touring Brackets T1 System bindings slide sideways into the offset touring bracket and are locked into place with our snap ramp. No pins, no cables, no fiddle factor.
