Rossignol BC Magnum Binding: is an extra-wide screw-mounted backcountry binding. The open/close mechanism has a large hand grip making it user-friendly even while wearing gloves. With a wide 67mm contoured steering plate skiers get increased contact between boot sole, binding and ski resulting in excellent stability and ski control, essential to traveling through variable snow conditions. Although designed for use on wider skis, the Magnum is compatible with skis down to a 52mm waist width. The BC Magnum's lightweight, easy-to-use and wider extra-stable design make it the the best binding on the market for backcountry exploring on wider BC skis.
