 Specs

Lightweight and Surfy

  • CNC machined baseplates with maximum cutouts shave weight, yet maintain strength and performance. All of the baseplate side windows have been partially filled to increase durability and strength. Cutouts also conveniently allow for puck adjustment with bindings in place for precise stance placement.
  • Features a medium flex version of our NEW Asym Rip ‘N’ Flip Highbacks for a surfy ride down. Ideal for riders who prefer more mobility.
  • 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 with 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 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 deployment and transitions.
  • NEW 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.
  • Ladders and adjusters are produced in-house with unique thermoplastics that maintain flex over a wide temperature range.
  • Incorporates Burton’s time-tested bomber buckles.

New Baseplate refinements

Here is a look at the baseplate refinements Spark has created.

  1. Partially filled side windows for increased durability, eliminating any weak points.

  2. Integrated detent for a stronger and longer lasting “snap” when locking into tour and ride mode, eliminating that single point of contact.

  3. Simplified toe ramp pivot geometry so you can removable ladders and adjusters more easily.

  4. Adjusted toe strap stop points for decreased forward rotation for XS, S and M sizes.  (the toe strap now fits better on smaller boots and won’t slip over your toe while touring).

  5. Narrowed the width and adjusted the stop points to accommodate the new ST whammy bar.

New ST Whammy Bar

The all new ST Whammy Bar has a single fatty wire with a side arm lever. Overmolded slippery plastic sections allow you to switch easily from stowed, to low (12°), or to high (18°) climbing positions and back again while touring.  

New Asym Highback Design

Asym Rip ‘N’ Flip Highbacks feature all of the same great splitboard-specific features our original Rip ‘N’ Flip highbacks are known for, but now have been redesigned for improved ergonomics, mobility, and durability

New features

  • Asymmetrical design features individual left and right highbacks that slope inward matching the rider’s stance.
  • The upper section is flatter for improved lateral mobility.
  • More material at the base for increased longevity and durability.
  • Higher bottom edge won’t snag on boots with crampon welts or soles that wrap high on the heel.

New Spark R&D Smooth Touring or ST 

Spark identified an opportunity to tweak how they make split board bindings.  They were able to improve the thermo plastic molding process, combining plastic injection with existing aluminum parts, which then created what is called 'over molding'. The Overmold plastic blend includes additives that will perform in cold weather, more durable, abrasion resistant, and even self lubricating. The innovative over molding process process allows for the creation of ST or Smooth Touring. Less friction mens less wear on the bindings and more results with less effort.
