Improved ST (Smooth Touring) Mode – Spark injection molds a proprietary thermoplastic over existing aluminum or steel parts in a process called "overmolding," reducing friction and improving durabillity.

ST Whammy Bars – A single fatty wire with a side arm lever. Overmolded thermoplastic sections allow you to switch easily from stowed, to low (12°), to high (18°) climbing positions and back again while touring. Includes an overmolded sleeve of plastic on both sides of the bar, right where the climbing wire contacts the baseplate. This reduces friction allowing for super smooth movement into and out of high, low, and stowed positions.

Snap Ramps – Bindings slide sideways into offset touring brackets and are locked into place with our snap ramps.

T1 Heel Rest – Catches the climbing wire in the 12° and 18° positions.

ST Whammy Bar Climbing Wire – Built right into the baseplate. Overmolded plastic where the bar contacts the baseplate allows for super-smooth climbing wire deployment and transitions.

ST Touring Brackets – Incorporates the best features of aluminum and thermoplastics. Spark R&D overmolds their custom plastic blend over and through the holes in the aluminum base, forming bushings that are incredibly durable.

CNC Machined Baseplate – Maximum cutouts shave weight, yet maintain strength and performance. Cutouts conveniently allow for puck adjustment with bindings in place for precise stance placement.

Pillow Line Straps – 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.

Ladders & Straps – Produced with unique thermoplastics that maintain flex over a wide temperature range

Bomber Buckles – These incorporate Burton's time-tested bomber buckles.

Arc ST Asym Rip ‘N’ Flip Highbacks – These have a moderate amount of glass fiber fill for medium flex and a surfy feel. They feature individual left and right highbacks for natural ergonomics with a flattened top section giving riders great lateral mobility
