Spark Arc ST Pro
Surfy & High Performance · Splitboard Bindings · Unisex Sizing
The lightest and highest performing splitboard bindings in the world — made with incredible attention to detail and no compromises. The Arc ST Pro features all the same great assets as the standard Arc ST Bindings — Smooth Touring (ST) Tech, T1 Binding System, Tesla Snap Ramps, maximum baseplate cutouts, surfy Asym Highbacks, and Pillow Line Straps with a flex window — but tuned up with premium materials and custom components.
Note: this binding does not include mounting pucks — you'll also need a set of Spark Flat Pucks or Spark Canted Pucks to mount it to your splitboard.
Product 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 — switch easily between stowed, low (12°), and high (18°) while touring.
T1 System & Tesla Snap Ramp
T1 System bindings slide sideways into the offset Tesla touring bracket and lock into place with the snap ramp — no pins, no cables, no fiddle factor. Integrated Ibex crampon mounting claws on touring brackets make for easy installation and removal, and pivot pins are hollowed out for 33% lighter weight.
Asym Rip 'N' Flip Highbacks
Made from carbon-reinforced nylon in a ratio designed for medium flex and a surfy feel — more responsive, lighter, and stiffer than standard glass-reinforced highbacks. Individual left and right highbacks improve ergonomics, comfort, and control, with a tool-free forward lean adjuster (FLAD) that toggles between tour and ride mode.
Pillow Line Straps
Made with premium Pebax® plastics — lightweight, durable, comfortable, waterproof, one-piece molded construction, made 100% in-house. Ankle straps feature a flex window for max agility while maintaining support; toe straps double as a toe cap or a traditional strap.
Custom Hardware
Custom-made 7075-T6 aluminum hardware replaces stainless steel for a 65% weight savings, with hex drives instead of phillips heads for less stripping.
