Endorsed by hard chargers everywhere, the Spark R&D Surge ST Splitboard Bindings have undergone sufficient change to warrant an upgrade to "ST" - smooth touring - status. Spark's own overmolding process puts low-friction, high strength plastic over existing metal components to reduce friction and increase durability pretty much anywhere the binding moves, making touring smoother, easier and quieter. Still the stiffest of the Spark offerings, the Surge ST also has a re-designed Asym highback and overmolded ST Whammy Bars where the bar meets the baseplate. A no-compromise approach to the riding after the approach.
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.
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
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
Tool free micro-adjustable from 0° to 22° for complete customization of your forward lean angle
Flippin’ FLAD toggles between your forward lean angle and -13° touring position for easy transitions.
Made with proprietary custom blended materials for improved strength and durability, while minimizing weight.
Lateral slots for our BD Touring Strap for greater edge control while skinning.
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.
Ladders and adjusters are produced in-house with unique thermoplastics that maintain flex over a wide temperature range.
