Spark R&D Arc ST

Arc ST Splitboard Binding 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 our industry-leading Tesla T1 technology. spark R&D 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.

The 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.

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. 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.

The product only includes the bindings, it does not include the splitboard pucks that are needed to attach the bindings to the splitboard.
