Tour Mode:
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 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.
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 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.
Baseplate:
CNC Machined Baseplates: Machined cutouts for maximum weight savings.
Straps:
Arc ST Pillow Line Straps: Ankle straps deliver weight savings and flexibility through a smaller footprint and flex window for maximum agility. Pillow Line straps are durable, waterproof, one-piece construction for all-day comfort so you can focus on the ride.
Buckles:
Ladders & Adjusters: Produced with a unique custom blend of thermoplastics that maintain flex over a wide temperature range.
Highback:
Arc ST Asym Rip N' Flip Highbacks: Molded with a moderate glass fiber for a medium and surfy response. Features an asymmetrical shape giving riders a natural stance for both left and right boots. The forward lean adjuster is tool free and easily flips between tour and ride mode.
Compatibility:
Requires Pucks for Mounting in Ride Mode: Spark Canted Pucks or Regular Pucks recommended (available to purchase separately)
