PRO SERIES BINDINGS
Spark Arc and Surge bindings are considered the best splitboard bindings you can buy. Spark manufacture pored over Arc and Surge bindings from end to end and put each component under the microscope. The Pro Series bindings are the lightest and highest performing splitboard bindings in the world - made with incredible attention to detail and no compromises.
CARBON REINFORCED HIGHBACKS
The Pro Rip ‘N’ Flip Highbacks are made of Carbon reinforced nylon making them even more responsive, lighter, and stiffer than our standard glass reinforced versions. Injection molding allows for more complex geometry and improved impact strength compared to other methods of carbon fiber construction.
7075 HEEL LOOPS
7075 aluminum is extremely strong and is often used for parts in the aircraft and aerospace industries. Using this premium alloy in the heel loops allowed us to make them thinner and lighter without sacrificing strength and reliability.
Spark manufacture used full Pebax® plastics in Pillow Line straps, ladders, and adjusters. Pebax® is a premium material most often found in high-end ski boots as it provides consistent stiffness and improved toughness in cold temperatures. It’s also 20% lighter than our standard material.
Weight savings add up by replacing stainless steel hardware with custom-made 7075-T6 aluminum hardware. Aluminum parts are 65% lighter than our standard stainless parts.
From Stainless Steel to Aluminum:
• forward lean nuts
• forward lean screws
• ankle strap t-nuts
From Stainless to Aluminum now with a hex drive head:
• heel rest screws
• touring bracket screws
• ankle strap screws
Perhaps the most custom splitboard binding-specific screws you’ll ever see are our aluminum heel loop screws. The custom screw head shape is optimized with more than double the drive depth of a standard button head screw to avoid stripping. We added an unthreaded shoulder to improve the connection with the heel loop. To top it off, we have a custom loctite patch added. If these screws come out, it’s because you take them out.
