Spark R&D Surge ST Pro Splitboard Bindings – Ultralight Power for Big Mountain Splitboarding
The Spark R&D Surge ST Pro Splitboard Bindings take the powerful, responsive ride of the standard Surge ST and upgrade it with premium lightweight materials for riders who want maximum downhill performance without carrying unnecessary weight uphill. Built around Spark's proven T1 binding system and Smooth Touring (ST) technology, the Surge ST Pro is designed for aggressive splitboarders tackling big terrain, long approaches, and demanding backcountry conditions.
Carbon-reinforced highbacks, lightweight 7075 aluminum heel loops, Pebax® plastics, and custom aluminum hardware bring the medium binding down to approximately 610 g per binding / 1220 g per pair. That's roughly 158 g lighter per pair than the standard Surge ST while maintaining the solid baseplate and supportive feel that make the Surge Spark's more powerful binding platform.
Surge Performance Without the Standard Surge Weight
The Surge ST Pro starts with a solid CNC-machined baseplate designed for stiffness, durability, and direct power transfer. Compared with Spark's lighter, more flexible Arc platform, the Surge is the better choice for larger or more aggressive riders and anyone who prioritizes response and control when riding steep or technical terrain.
The Pro treatment then removes weight from the components surrounding that stiff platform. The result is a binding that maintains the powerful character of the Surge while making long approaches, big vertical days, and multi-day objectives noticeably more efficient.
Carbon-Reinforced Asym Rip 'N' Flip Highbacks
The Surge ST Pro Asym Rip 'N' Flip Highbacks use carbon-reinforced nylon for increased stiffness and response at a lower weight than Spark's standard glass-reinforced highbacks. Their asymmetrical shape is designed around left- and right-foot ergonomics for improved comfort and control.
Spark's Rip 'N' Flip system makes switching between touring and riding straightforward, allowing you to quickly change from a more touring-friendly highback position to the forward lean you want for the descent.
Premium Pro Series Materials
The biggest difference between the Surge ST Pro and Surge ST is found in the details. Spark replaces several standard components with lighter premium alternatives, shaving grams throughout the binding without compromising its aggressive riding character.
- 7075 Aluminum Heel Loops: Thinner and lighter than Spark's standard heel loops while retaining the required strength.
- 7075-T6 Aluminum Hardware: Custom aluminum hardware replaces stainless steel in key locations and is approximately 65% lighter than Spark's standard stainless hardware.
- Hollow Pivot Pins: Hollowed stainless steel pivot pins are approximately 33% lighter than Spark's standard versions.
- Pebax® Plastics: Premium thermoplastic is used throughout the straps, ladders, and adjusters for dependable cold-weather performance at approximately 20% less weight than Spark's standard material.
- Carbon-Reinforced Highbacks: Lighter, stiffer, and more responsive than Spark's standard glass-reinforced highbacks.
Together, these upgrades are what turn the already capable Surge ST into Spark's premium high-performance Surge platform.
Smooth Touring (ST) Technology
Spark's Smooth Touring technology uses a proprietary thermoplastic blend overmolded onto metal components in high-friction areas. The material is engineered to be cold tolerant, abrasion resistant, durable, and self-lubricating, helping the binding pivot smoothly while touring.
For long approaches and high-vertical days, reduced friction means a smoother stride and less resistance through thousands of touring steps. It's a subtle improvement on any individual stride, but one that becomes increasingly valuable as the day gets longer.
Tesla T1 – Fast, Simple Splitboard Transitions
The Surge ST Pro uses Spark's proven Tesla T1 system. In tour mode, the binding slides sideways into the offset touring bracket and locks into place using the integrated Snap Ramp—there are no removable binding pins or cables to manage.
Integrated crampon mounting claws on the touring brackets make adding compatible Spark Ibex crampons straightforward when the skin track gets firm, while the T1 heel rests work with Spark's climbing wires for steeper ascents.
Supportive Pillow Line Straps
Wide, asymmetrical Surge Pillow Line ankle straps wrap securely around the boot for the support and control aggressive riders expect from the Surge. The toe straps can be worn over the end of the boot as a toe cap or traditionally across the top.
Pro Series Pebax® components maintain consistent performance across a wide temperature range, making the binding equally at home on frigid mid-winter missions and warm spring objectives. Spark pairs them with proven Burton buckles for dependable adjustment in the backcountry.

Surge ST Pro vs Surge ST – What's the Difference?
Both bindings share the stiff, powerful Surge platform, T1 system, Smooth Touring technology, solid baseplate, and supportive Surge geometry. The Surge ST Pro upgrades key components to premium lightweight materials including carbon-reinforced highbacks, 7075 aluminum heel loops, Pebax® plastics, hollow pivot pins, and custom aluminum hardware.
The standard Surge ST weighs approximately 689 g per binding in Medium versus approximately 610 g for the Surge ST Pro. That's a saving of roughly 79 g per foot or 158 g per pair—weight you're lifting with every stride on the skin track.
Important: Spark Pucks Sold Separately
The Surge ST Pro includes the splitboard bindings, ST touring brackets, T1 heel rests, aluminum mounting screws, and Spark Pocket Tool. You'll also need a compatible set of Spark Flat Pucks or Spark Canted Pucks to attach the bindings to a puck-compatible splitboard in ride mode.

Spark R&D Surge ST Pro Splitboard Bindings – Frequently Asked Questions
Who are the Spark Surge ST Pro bindings best for?
The Surge ST Pro is designed for riders who prioritize power, response, and downhill control but still want to minimize touring weight. It's particularly well suited to aggressive freeriders, larger riders, steep terrain, big mountain lines, and long backcountry objectives.
What is the difference between the Surge ST Pro and Surge ST?
Both use the same powerful Surge platform, but the Pro version upgrades key components with lighter premium materials. Carbon-reinforced highbacks, 7075 aluminum heel loops, Pebax® plastics, hollow pivot pins, and custom aluminum hardware reduce weight while maintaining the stiff and responsive character of the Surge.
How much do the Spark Surge ST Pro bindings weigh?
Spark lists the current Surge ST Pro at approximately 610 g (1.34 lb) per binding or 1220 g (2.68 lb) per pair in size Medium.
What is Spark Smooth Touring (ST) technology?
Smooth Touring uses Spark's proprietary thermoplastic overmold on metal components in key friction areas. The material is designed to be cold tolerant, durable, abrasion resistant, and self-lubricating, reducing friction through the touring motion.
Do Spark Surge ST Pro bindings include pucks?
No. The bindings include ST touring brackets, T1 heel rests, aluminum mounting screws, and a Spark Pocket Tool, but Spark Flat Pucks or Spark Canted Pucks are sold separately.
Will the Surge ST Pro fit my splitboard?
Spark R&D bindings are designed for puck-compatible splitboards. With correctly installed compatible pucks, the bindings slide onto the board in ride mode and lock into position using the Tesla Snap Ramp.
Are the Surge ST Pro bindings good for long tours?
Yes. Although the Surge is Spark's stiffer, more powerful platform, the Pro construction significantly reduces weight. At approximately 1220 g per pair in Medium, the Surge ST Pro is an excellent option for riders who want efficient uphill performance without giving up a supportive, aggressive binding for the descent.
Should I choose the Spark Surge ST Pro or Arc ST Pro?
Choose the Surge ST Pro if you prioritize stiffness, support, high-speed control, and aggressive freeriding. The Arc platform is the better choice for riders who prioritize lower weight, greater flexibility, and a more surfy or playful feel. Spark specifically positions the Surge as its stiffer option for bigger and more aggressive riders.
Are Spark Surge ST Pro bindings compatible with splitboard crampons?
Yes. The included ST touring brackets incorporate Spark's crampon mounting interface, allowing compatible Spark Ibex splitboard crampons to be installed when extra traction is needed on firm or icy skin tracks.
Where are Spark R&D splitboard bindings made?
Spark R&D manufactures and assembles its splitboard bindings in-house in Bozeman, Montana. The company has been focused on splitboard binding and accessory development since 2006.
