Spark R&D Arc ST Splitboard Bindings Spark R&D's industry-leading splitboard binding excels in the trees and powder, but is tough enough to handle more complex all-mountain conditions. Cutout baseplate design, medium flex Asym Rip 'N' Flip Highbacks, and a smaller ankle strap with a flex window combine to save valuable grams and deliver a surfy ride down. All Arc ST Bindings incorporate our industry-leading Tesla T1 technology. Our Smooth Touring (ST) Tech is featured on our ST Brackets and ST Whammy Bars. These components utilize a proprietary thermoplastic blend that is molded over the metal part reducing friction, increasing durability, and improving touring efficiency. **Spark Pucks are needed and sold separately** Tour Mode 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. ST Whammy Bars – Overmolded plastic blend where the climbing wire meets the baseplate to eliminate stickiness. (Note: not backward compatible with previous Arc, Surge or other older models) ST Touring Brackets – Overmolded with low-friction proprietary plastic over and through the bracket holes in the aluminum base - strong, smoother pivoting, and lasts 4 times longer than the old brass bushing. Baseplate CNC Machined Baseplates – CNC machined baseplates remain solid for max stiffness and durability. All of the baseplate side windows have been partially filled to increase durability and strength Straps Pillow Line Straps – Pillow Line Straps are lightweight, durable, comfortable, waterproof, one-piece molded construction, and made 100% in-house. Surge ST ankle straps are wide and asymmetrical around the boot for incredible all-around support. Toe straps are designed to be used as a toe cap, but also fit nicely as a traditional strap across the top of the boot. Buckles Proven Burton Buckles Buckles and Plastics – Ladders and adjusters are produced in-house with unique thermoplastics that maintain flex over a wide temperature range. Highback Asym Rip 'N' Flip Highbacks – Asymmetrical design features individual left and right highbacks that slope inward matching the rider’s stance / The upper section is flatter for improved lateral mobility / More material at the base for increased longevity and durability / Higher bottom edge won’t snag on boots with crampon welts or soles that wrap high on the heel Flippin’ FLAD toggles between your forward lean angle and -13° touring position for easy transitions. Lateral slots for our BD Touring Strap for greater edge control while skinning. Made with proprietary custom blended materials for improved strength and durability, while minimizing weight. Tool free micro-adjustable from 0° to 22° for complete customization of your forward lean angle Compatibility Puck Compatibility – Slide them on and snap the ramp down. Snap the ramp up and slide them off. The most functional way to attach your binding to your board in ride mode. Period. Spark R&D bindings are designed to work with all puck compatible splitboard models. Size Chart
