Spark R&D Arc ST Bindings 2026

The Spark R&D Arc ST splitboard binding is designed to take on challenging all-mountain conditions, yet remain agile in the trees and powder. Featuring a lightweight cutout baseplate, Asym Rip 'N' Flip Highback and smaller, but responsive, ankle strap, this binding is ultra light for improved manoeuvrability and response. The new and improved, industry leading Smooth Touring (ST) Tech and ST Whammy Bars deliver smooth touring performance with less friction and increased durability.

Binding Type: Backcountry / Splitboard

Board Compatibility: Compatible with splitboards using Spark pucks, Spark canted pucks, or Voile pucks.

Weight: 628g per binding

High Back: Asym Rip 'N' Flip

The Asym Rip N Flip Highback on the Arc ST offers a medium flex and a surfy feel, thanks to its moderate amount of glass fiber fill. The improved asymmetrical highbacks feature individual left and right highbacks for superior ergonomics. It also features a tool free forward lean adjuster for customisable forward lean from 0° to 22° in ride mode, and toggles between forward lean and -13° touring position for easy transitions.

Buckles: Bomber Buckles

Ladders and adjusters are produced in house with Pebax premium thermoplastics that are 20% lighter than the standard material and maintain flex over a wide temperature range, performing well from spring tours to mid-winter missions. Spark bindings feature Burtons Bomber Buckles, which have passed the test of time and ensure reliability.

Straps: Pillow Line Straps

Surge Pebax Pillow Line Straps are made with Pebax plastics, a premium material most often found in high end ski boots. Renowned for its consistent stiffness and improved toughness in cold conditions, it is also 20% lighter than traditional plastic. Ultra durable, comfortable, waterproof, and made completely in-house, the Pillow line straps are painstakingly designed for a comfortable fit as well as fast and consistent response. Surge ankle straps have a wide, asymmetrical footprint around the boot for incredible all round support. The Toe strap features over the top and cap strap functionality.

Additional Features:

Whammy Bar Climbing Wire:

A single fatty climbing wire is built into the baseplate with a side arm lever for easy position changes. Easily switch between stowed, low (12°), and high (18°) and back again.

Snap Ramps, Touring Brackets, and Pivot Pins:

T1 System bindings slide sideways into the offset Tesla touring bracket and are locked into place with a snap ramp, negating the need for pins and cables. Integrated Ibex crampon mounting claws on touring brackets make for quick and easy installation and removal. Pivot pins have been hollowed out and are 33% lighter than standard pins.

Puck Compatibility:

Slide them on and snap the ramp down, or snap the ramp up and slide them off, regardless of whether you're putting them on or taking them off, it'll be super easy and quick. When used with Arc bindings you'll be able to conveniently access puck screws with the bindings in place for precise stance adjustment.

T1 Heel Rest:

The T1 Heel Rest catches the climbing wire in the 12° and 18° positions and is specifically designed to hold the T1 step locker in place.
