Taking the Prime System to the next level, the Karakoram Prime-X Splitboard Binding separates itself from the SL by shaving off 85 grams of weight and increasing the stiffness of the chassis. Then, a 7075-T6 aluminum toestay adds flex underfoot to absorb harsh chatter and keep foot fatigue at bay, while a Reaction highback supports, flexes where you need it, and responds insanely fast. This results in a performance that allows you to travel lighter, faster, and longer, and most importantly, ride harder than anyone else. Equipped with a Reaction highback, the Prime-X's high-quality Dupont Zytel ST highback optimizes its strength-to-weight ratio, and maintains a medium flex for lateral support when you need it most. A stiffer flex is found in the Open Binding chassis for unrivaled response and an uncompromising board feel, while the X-Type Heelcup offers high sidewalls for more support and better power transfer while side-hilling. This heelcup is also made from 7075-T6 aluminum, which is twice as strong as standard aluminum, and is cored out for featherweight performance. The Prime-X features Dual Ride-Stride forward lean that quickly toggles between Ride and Walk modes with a 1/4-turn of the forward lean adjuster. In Walk mode, the -8 degree forward lean elongates your stride to conserve energy on the long uphill skin. Ride mode delivers 0 to 22 degrees of forward lean (2 degree adjustable increments) for quick-turning response when you're charging steeps. Then, its Solid Ride four-point attachment increases your stance options (-30 to 30 degrees) and improves ergonomics. Four wide preloaded contact points direct energy to the edges for unmatched response and control when you're riding high-consequence terrain. The Flip-Speed Riser deploys with the simple flick of your pole basket to get you moving upwards with zero hassle, and features different heights for different terrain. Engage the shorter riser on long, flatter approaches or flip the taller riser during ...
