Arc Dusk Splitboard Binding blends cutout baseplates, medium-flex Asym Rip ’N’ Flip Highbacks, and the flex-window ankle strap into a responsive yet surfy chassis.

ST Touring Brackets combine aluminum with overmolded thermoplastics so the bushings last four times longer.

ST Whammy Bars keep the climbing wire pinned into the baseplate, letting you move smoothly between stowed, low (12°), and high (18°) walking positions.

Pillow Line Straps are lightweight, waterproof, and molded as a single piece so the flex window stays supple while a toe cap can switch to over-top mode.

Slide on Spark Pucks, snap the ramp, and ride — the Tesla Snap Ramp with Ibex crampon mounts keeps the system precise.

The T1 Heel Rest catches the climbing wire at 12° and 18° and keeps the Step Locker secured while you tour.

Buckles and plastics are produced in-house from Pebax thermoplastics that maintain flex from spring tours through sub-zero suffer fests.

Sizing and Setup

Available in XS through L, because splitboarders don’t need men’s or women’s versions — just the right fit.

ST Bindings

*** ST bindings work only with ST Whammy Bars; 21/22 and earlier T1 bindings need a standard Whammy Bar.

*** ST bindings stay compatible with older Tesla brackets that still use brass bushings.

Arc ST Asym Rip ’N’ Flip Highbacks

Carbon-reinforced nylon keeps the Highbacks light, responsive, and ergonomic for left/right specific control with a tool-free FLAD.

ST Touring Brackets

The overmolded plastics form super-durable bushings that don’t wear out mid-season.

ST Whammy Bars

Built‑in climbing wires and overmolded housings keep transitions buttery smooth.

Pillow Line Straps

Premium Pebax straps stay lightweight, flexible, and waterproof while the flex window locks you in.

ST Brackets & Tesla Snap Ramp

T1 bindings slide into the offset Tesla bracket, lock with the Snap Ramp, and keep the build super stiff.

T1 Heel Rest

The heel rest secures the climbing wire at both 12° and 18° while catching the Step Locker.

Buckles & Plastics

In-house thermoplastics on ladders and adjusters keep their flex in cold temps and pair with 7075-T6 and Grade 5 Titanium hardware for direct power transfer.
