Spark Surge ST

The Surge ST is trusted by professional big line riders and mountain town legends alike. It’s a powerful binding with a more robust ankle strap and stiff highback, perfect for big days and big lines. The new ST Touring Bracket and ST Whammy Bars make this binding even more efficient while touring to the steeps.

New For 2023: 

Spark made some great updates to the line with new asymmetric highbacks, baseplate refinements that improve durability and the all-new ST Tech. ST stands for Smooth Touring and will be seen in the touring brackets, the whammy bars and the crampons. This process of overmolding allows them to inject plastic over the metal parts for the best combination of strength and smooth rotation. 

Updated Sizing:

Spark has moved to a unisex binding line. The size charts have been meld into one, from XS to L. Bindings are now available in all the same colorways for men and women.

Tesla T1 System: Bindings slide sideways into the offset touring brackets and are locked into place with the snap ramp (the part right under your toes). No pins, no cable, no fiddle factor. To ride, slide across Spark or Voilé pucks (sold separately) and again, press down the snap ramp.

ST Whammy Bar Climbing Wire: A single fatty wire with a side arm lever that allows you to easily switch from stowed to low (12°), to high (18°) climbing positions and back again while touring. Overmolded plastic where the bar contacts the baseplate allows for super-smooth climbing wire deployment and transitions.

ST Touring Brackets: Incorporate the best features of aluminum and thermoplastics. A plastic blend is molded over and through the holes in the aluminum base, forming bushings that last four times longer than their previous brass version.
Hi-Back
The Surge features a stiffer version of the Rip N’Flip Highback for riders who prefer maximum response.

New Asym Rip ‘N’ Flip Highback: 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. The tool free forward lean adjuster (FLAD) offers complete customization from 0 to 22° in ride mode. The FLAD toggles easily between lean position and -13° touring position for easy transitions.

Lateral slots accomodate Strappy Straps for additionnal comfort on firm skin tracks (sold separately).
Straps
Pillow Line Straps: They are ultradurable, comfortable, waterproof and a one-piece molded construction. Thin and flexible for comfort, while the thicker ribs are held off the boots and provide stiffness for a uniquely responsive ride. The Surge ankle straps have a wide footprint around the boot for incredible all around 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.

Incorporates Burton’s time-tested bomber buckles.
