The Spark R&D Arc ST Splitboard Bindings are an industry-leading model that excels in the trees and powder, but is tough enough to handle more complex all-mountain conditions. Cutout baseplate design, medium flex Asym Rip 'N' Flip Highbacks, and a smaller ankle strap with a flex window combine to save valuable grams and deliver a surfy ride down. All Arc ST Bindings incorporate Spark R&D's industry-leading Tesla T1 technology. Our Smooth Touring (ST) Tech is featured on the ST Brackets and ST Whammy Bars. These components utilize a proprietary thermoplastic blend that is molded over the metal part reducing friction, increasing durability, and improving touring efficiency.

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 ST Asym Rip ‘N’ Flip Highback has a moderate amount of glass fiber fill for medium flex and a surfy feel. The bindings feature individual left and right highbacks for improved ergonomics, comfort, and control. The upper section of the highback is flatter giving riders excellent lateral mobility. All Rip ‘N’ Flip Highbacks incorporate a tool-free forward lean adjuster (FLAD) that easily toggles between tour and ride mode.
ST Touring Brackets incorporate the best features of aluminum and thermoplastics. We overmold our custom plastic blend over and through the holes in the aluminum base, forming bushings that last four times longer than their previous brass version.
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.
Snap Ramps & Side-Lock Tesla Touring Brackets: T1 System bindings slide sideways into the offset touring bracket and are locked into place with the 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.
