Spark R&D Surge ST Splitboard Bindings in Violet

The Spark R&D Surge ST Splitboard Binding in Violet is built for big-mountain riders, splitboarders who carry heavier packs, and anyone charging steep, technical terrain. Engineered around Spark's pinless Tesla T1 chassis and equipped with Smooth Touring (ST) technology, the Surge ST features a solid baseplate, glass-filled stiff highbacks, and wider ankle straps to give you uncompromising edge control, power transfer, and reliability in the backcountry.

Milosport Shop Take

"If you're riding aggressive freeride splitboards, dropping technical lines at Snowbird backcountry, or charging high-speed turns through firm snow, the Surge ST is the heavy-hitter you want underfoot. The Violet colorway adds a sick pop of color to any split setup.

Compared to the surfier Arc ST, the Surge ST gives you a noticeable jump in drive and power. It uses a solid CNC-machined baseplate and glass-filled Rip 'N' Flip highbacks to eliminate flex delay when driving your edges into hardpack steeps. Coupled with Spark's overmolded ST Touring Brackets and ST Whammy Bars—which cut friction and make switching climbing wire heights with a pole basket completely seamless—the Surge ST is pure power for serious touring missions."

Technical Specifications

Under the Hood

• Solid CNC Machined Baseplate: Eliminates baseplate cutouts to deliver maximum power transfer, rigidity, and stability when driving hard edge angles on steep descents.

• Tesla T1 System: Pin-free snap-ramp mechanism allows you to slide the binding sideways into the touring bracket and lock it down instantly.

• Smooth Touring (ST) Tech: Thermoplastic custom blend is overmolded over aluminum in the ST Touring Brackets and Whammy Bars, reducing pivot friction and increasing durability up to four times over legacy brass bushings.

• Glass-Filled Surge Highbacks: High-percentage glass fiber fill yields a super-stiff, responsive highback with tool-free Forward Lean Adjuster (FLAD) that flips from a -13° striding angle to a custom downhill angle.

• Surge Pillow Line Straps: 100% in-house 3D molded, waterproof, one-piece straps. The Surge ankle strap features a wider, asymmetrical power-spine footprint to lock down boots on heavy lines.
