Spark R&D Surge ST Splitboard Bindings - 2027

The 2027 Spark R&D Surge ST splitboard bindings are built for riders who refuse to dial it back, channeling raw power into every turn and every skin track. A solid CNC-machined baseplate locks in stiffness where it counts, while the high glass fiber Asym Rip 'N' Flip Highbacks deliver maximum response with the torsional give you need riding back down. The Tesla T1 Tech system switches heel lift modes with a pole tip, keeping transitions fast when the mountain demands it. For aggressive alpinists and big-mountain splitboarders who want no compromise.

CNC Machined Baseplates: Solid aluminum baseplate machined for maximum stiffness, denser and more rigid than the cutout Arc ST design, transferring power directly into the board with zero flex loss.

Surge ST Asym Rip 'N' Flip Highbacks: High glass fiber fill molding delivers a stiff, maximally responsive ride. Individual asymmetrical left and right highbacks angle inward for a natural stance on both feet. Forward lean is tool-free micro-adjustable from 0° to 22° and flips to -13° for touring transitions. Stiff toe-to-heel with torsional flexibility for riding mobility. Lateral slots accept BD Touring Strap. Patented.

Surge ST Pillow Line Straps: Ankle straps with a solid asymmetric one-piece molded construction for a secure, supportive fit. Thin flexible cushions conform to the boot; thicker ribs maintain structure away from the foot. Lightweight, ultra-durable, waterproof and will not freeze

Ladders and Adjusters: Produced in-house with Spark R&D's proprietary thermoplastic blend, engineered to maintain consistent flex performance across a wide temperature range.

ST Tech Components: Snap Ramps: locking ramps that secure bindings to touring brackets; flip ramp down to ride, flip up to remove · ST Brackets: touring brackets with thermoplastic overmolding for smooth, durable glide, compatible with all Tesla T1 bindings · ST Whammy Bars: heel lifter bars overmolded at both ends to reduce friction and enable seamless transitions between stowed, low (12°) and high (18°) positions

Tesla T1 Tech System: Spark R&D's most recognized splitboard touring system. Integrated ST Whammy Bar side arm levers let you switch from stowed, to low (12°), to high (18°) heel lift and back using just a pole tip, hands-free on the skin track
