SPARK R&D Arc x NITRO 2025 | splitboard bindings | XS/S EU35-40

Lightweight and Surfy | The women’s / junior's Arc has all of the same great features as our men's Arc - CNC machined baseplate with max cutouts, surfy highback, and lower profile ankle strap - but sized specifically for women’s boots. Shorter and narrower baseplates fit snug and comfortably, accommodating down to a size 5 US (22 Mondo) boot. Lower and more compact heel loops move the ankle strap mounting point down to hit the sweet spot over your boot while positioning the highbacks lower on the leg for a better calf fit. All Women's Arc bindings incorporate our industry-leading Tesla T1 technology. Every piece of this binding is made in-house with the exception of a few screws and the buckles!

Pillow Line Straps

Arc Pillow Line Straps are lightweight - 46% lighter than their fabric strap predecessors. They are ultradurable, comfortable, waterproof, one-piece molded construction, and made 100% in-house. Strap pillows are thin and flexible for a comfortable, conformed fit, while thicker ribs are held off the boot and provide stiffness for a uniquely responsive ride. Arc ankle straps are smaller around the boot than the Surge and feature a flex window for max agility while maintaining support. The toe straps come in one construction for both Arc and Surge models, and are designed to be used as a toe cap but also fit traditionally over the top.

Rip 'N' Flip Highback

The R&D shines with a shape built from 3D scans of popular splitboard boot models, and a list of rad features designed specifically for and fully appreciated by the splitboarder. The Arc highback has a moderate amount of glass fiber fill for medium flex and a surfy feel. The tool free forward lean adjuster (FLAD) offers complete customization from 0° to 22° in ride mode. The Forward Lean Adjuster toggles easily between forward lean position and -13° touring position for easy transitions.

Whammy Bar Climbing Wire

A single fatty climbing wire is built into the baseplate with a side arm lever for easy position changes on the steeps. You can switch easily from stowed, to low (12°), to high (18°) and back again while touring.

Snap Ramps & Side-Lock Tesla Touring Brackets

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.

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. When used with Arc bindings conveniently access puck screws with the bindings in place for precise stance adjustment. Available in a flat and a 3° canted model. Note that pucks do not come with the bindings out of the box and must be purchased separately. 

T1 Heel Rest

The T1 Heel Rest catches the climbing wire in the 12° and 18° positions and is specifically designed to hold the T1 Step Locker in place.

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.
