The PRIME-X Carbon Splitboad Binding is Karakoram's premiere binding for diehard splitboarders. It's the lightest Karakoram binding available, and its extreme stiffness assures the unforgiving, instantaneous response that aggressive riders look for while dropping the steepest lines down the biggest mountains. For this reason, Karakoram threw on a carbon highback for a lighter weight, a better fitted heel cup for better power transfer, and a more open chassis that allows your splitboard to flex naturally. Specializing in efficiency, the Prime Interface uses the tried-and-true Tour Mode used on the original Split 30 interface. A quick-release touring bracket and Power-Link activation lever allow for quick-and-easy transitions from touring to riding mode. Best of all, the Prime Interface has no moving parts, so you never have to worry about losing parts in the snow.
