Features:

ST Whammy Bars: The ST Whammy Bar climbing wire is built right into the baseplate. Overmolded plastic where the bar contacts the baseplate allows for super-smooth climbing wire position changes in the steeps. You can switch easily from stowed, to low (12°), to high (18°), and back again while touring.
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.
Tesla Snap Ramp: T1 System bindings slide sideways into the offset touring bracket and are locked into place with our snap ramp. No pins, no cables, no fiddle factor. Integrated Ibex crampon mounting claws on touring brackets make for quick and easy installation and removal.
Custom Hardware: Weight savings add up by replacing stainless steel hardware with custom-made 7075-T6 aluminum hardware. Aluminum parts are 65% lighter than our standard stainless steel parts and are made with hex drives instead of phillips heads which are less likely to strip.
Buckles & Plastics: Ladders and adjusters are produced in-house with unique thermoplastics that maintain flex over a wide temperature range, performing well on spring tours as well as sub-zero suffer fests. All straps incorporate Burton's time-tested bomber buckles.

Highback: Asym Rip 'N' Flip Highbacks

The NEW Arc ST Asym Rip ‘N’ Flip Highback has a moderate amount of glass fiber fill for medium flex and a surfy feel. The Asym Highbacks have been redesigned in 22/23 and now feature individual left and right highbacks for improved ergonomics. The upper section of the highback is flatter allowing for increased lateral mobility. All Rip ‘N’ Flip Highbacks incorporate a tool free forward lean adjuster (FLAD) that easily toggles between tour and ride mode.

Straps: Pillow Line Straps

Pillow Line Straps are lightweight, durable, comfortable, waterproof, one-piece molded construction, and made 100% in-house. Arc ST Ankle Straps are smaller around the boot than the Surge ST and feature a flex window for max agility while maintaining 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..

Baseplate: ST Touring Brackets

ST Touring Brackets incorporate the best features of aluminum and thermoplastics. Spark overmold their custom plastic blend over and through the holes in the aluminum base, forming bushings that last four times longer than their previous brass version.

Flex: 5-7 (Scale 1 - 10)
