The name gives it away. The Karakoram PRIME Straightline + Split Interface Splitboard Bindings are a stiffer version of the Prime X-Carbon, custom made for riders going big in the backcountry. While they're out in front as the stiffest binding in the Karakoram lineup, downhill power doesn't come at the expense of uphill performance - these skin track speedsters weigh in at a very respectable 785g and come with touring friendly features like DualSpeed Risers and the rock solid Split Interface. With full carbon highbacks and a slightly burlier base for maximum response, the Karakoram PRIME Straightlines are perfect for the self-powered athlete looking for freeride greatness.
DualSpeed Risers with Heel-Lock – These risers open with a pole basket, have two heights, and have a retractable heel lock that you can flip up when you need it.
Flex-Lock – Ride like a snowboarder and tour like a hardbooter with this external stiffening device that gives you twice the edge grip.
Smooth Touring Pivot – Independent sleeves rotate freely on a fixed thru-axle, similar to a bike axle, making these stiff and smooth. They're wide for touring rigidity, they shed snow well, and the quick-releasing bracket allows for simple transitions.
Prime System – Quickly attach your Prime bindings to your solid board with Quiver-Connectors or splitboard with the Ride Mode 2.0.
Ride Mode 2.0 – Easy snow clearing, drop-on change-overs, and no slop. Ride Mode 2.0 ensures the most solid connection between all your components.
Interlocking Seam Tabs – No separation: tabs interlock across the seam of your board, interlocking and pre-loading the two halves for a solid ride.
Active Joining – No slop with instant response. Pre-loaded contact points create an ultra solid connection between your bindings and splitboard.
Power Link – Getting your binding in and out of ride mode has never been easier than with Power Link, an ergonomic activation lever that allows you to remove your bindings or engage with one simple, fluid motion. Pull up to lock, push down to unlock.
Open Chassis Design – Allows your board to flex naturally on its own, unaffected by bindings.
Straightline X-Type Heelcup – 2X stronger than standard aluminum, these CNC'd baseplates have higher sidewalls for better power transfer and support.
Aluminum Hardware – Custom 7075-T6 screws and hollow pins mean every gram counts.
Flex (1 Soft - 10 Stiff) – 10
Airform Straps – Independent Pressure Pods articulate to boot eliminating pressure points and pinch points.
Super Pivot Ratchets – Low profile Nylon composite ratchets are robust, smooth, and up to 30% lighter.
Carbon Highbacks – Biaxial weave carbon and multiple layers give the optimal high-performance combo of stiffness and support.
Dual Ride-Stride Forward Lean Adjustment – Go between ride, surf, and walk modes with a tool-free twist of the adjuster.
