The Atomic X 16 VAR is a high performance binding for Atomic adult Redster race skis that are mounted with the race plate. The Variable Positioning System allows you to slide the binding fore and aft on the plate to find your sweet spot on the ski for that particular event or the conditions that day. The Full Flexing action allows your Redster to flex naturally for full on edge contact and faster times through the course. A burly DIN range of 8-16 will keep the biggest and hardest charging racers locked in when you need to be. A powerful energy transfer only adds responsiveness to your pair of Redsters.
