Splitboard Binding Spark R&D Arc ST Pro  black

Spark R&D Arc ST PRO splitboard binding

The lightest and most sought-after splitboard binding that is designed with attention to detail. It has all the premium features of the classic Arc ST, but takes them to the next level with premium materials and bespoke components. This makes the binding even lighter and more powerful. Whether it's the lightweight aluminium bolts, the aluminium heel, the hollow pins or the carbon reinforcement in the highback - these improvements make the model for all splitboarders who want the best of the best.

New for the 22/23 season is the use of the new Smooth Touring (ST) technology, which extends the life of the components and reduces friction between them. This makes the climb smoother than ever before. Also new are all bindings in unisex only, making the choice a little easier again.

* Package includes: bindings, ST risers, T1 heel pads, mounting screws and Spark pocket tool

**Please note that pucks do not come with bindings and must be purchased separately.

Smooth Touring (ST)

For the 22/23 season, several binding components were modified using the overmolding technique. A special thermoplastic compound, which has ideal properties resistant to frost and abrasion, is injected onto aluminum or steel parts. This brings an even smoother feeling when climbing thanks to the reduction of mutual friction between the individual components. Their service life is thus extended and they bear the new designation Smooth Touring - ST.

Specifications

• Baseplate - CNC machined base has a maximum of cutouts for lightening without affecting strength and performance, the sides of the base are partially filled for greater durability. The cut-outs also allow manipulation of the pucks with the binding in place.
• Custom Hardware - Stainless hardware is replaced with custom designed 7075-T6 aluminum material that is 65% lighter
• Asym Rip 'N' Flip Highbacks - one of the novelties of this season are asymmetric ergonomic highbacks that are flatter at the top for better lateral mobility. The highbacks on the PRO model are reinforced with carbon for greater lightness and greater stiffness. FLAD - possibility to adjust the tilt of the highback completely without tools.
• ST Whammy Bars - heel riser support is built right into the base and allows for easy repositioning on steep slopes. You simply switch from horizontal to low (12°), high (18°) and back.
• ST Touring Brackets - new touring brackets use ST technology. A plastic compound is remelted through holes in the aluminum base, creating brackets that last four times longer than their previous brass versions.
