evo.com | Spark R&D Splitboard Bindings > The Spark R&D Arc ST Pro Splitboard Bindings take the surfy, playful feel of the Arc and crank it up with top-tier materials for the ultimate lightweight ride. With carbon-reinforced nylon highbacks and full Pebax(R) plastic throughout the straps and ladders, these bindings are featherlight without compromising strength or response. Perfect for riders who want to float through pow, weave through trees, and move fast and light in the backcountry. Improved ST (Smooth Touring) Mode Spark injection molds a proprietary thermoplastic over existing aluminum or steel parts in a process called "overmolding," reducing friction and improving durabillity. Requires Pucks for Mounting in Ride Mode Spark Canted Pucks or Regular Pucks recommended (available to purchase separately) Premium Materials & Custom Hardware Custom made hardware allows splitboard specific features to be added like hex heads for less strippage and hollow pivot pins for weight savings. The heel loop screws got the best makeover of all with a custom screw head with double the drive depth and an unthreaded shoulder to improve connection to the heel loop. Arc Pebax Pillow Line Straps Pebax is a premium material most often found in high-end ski boots as it provides consistent stiffness and improved toughness in cold temperatures. It's also 20% lighter than our standard material. CNC Machined Baseplate Maximum cutouts shave weight, yet maintain strength and performance.
