Sizing and Setup

Available in XS to L – no men’s or women’s version, just splitboard bindings for splitboarders.

ST Bindings

*** ST bindings are only compatible with ST Whammy Bars. 21/22 and older T1 bindings require a standard Whammy Bar.

*** ST bindings are compatible with older Tesla brackets with brass bushings.

Arc ST Pro Asym Rip 'N' Flip Highbacks

Carbon-reinforced nylon keeps the highbacks light, stiff, and responsive while asymmetrical shaping plus tool-free FLAD ensure control.

ST Touring Brackets

Aluminum and thermoplast combine with an overmolded custom plastic to produce bushings that last four times longer.

ST Whammy Bars

The ST Whammy Bar climbing wire is built right into the baseplate. Overmolded plastic keeps shifts from stowed to low (12 deg) to high (18 deg) buttery smooth.

Pillow Line Straps

Pebax Pillow Line Straps stay lightweight, waterproof, and asymmetrical with a flex window.

Custom Hardware

7075-T6 aluminum hardware saves weight, is 65% lighter than stainless steel, and uses hex drives.

Spark Pucks - Puck Compatibility

Slide on, snap the ramp, ride. Spark bindings work with every puck-compatible splitboard.

ST Brackets - Tesla Snap Ramp

T1 bindings slide sideways into the offset Tesla bracket and lock with the snap ramp. Integrated Ibex mounts keep installation fast.

T1 Heel Rest

The T1 Heel Rest catches the climbing wire at 12 deg and 18 deg and secures the Step Locker.

Buckles & Plastics

Pebax premium thermoplastics deliver long-lasting flex while saving 20% weight.
