The Rossignol NNN BC Automatic Ski Bindings are extremely user-friendly and easy to operate when out doing some rugged touring. The Rossignol NNN BC Automatic binding features a convenient automatic step-in design that closes with an audible click and releases with ski-pole pressure - no need to ever bend down and fumble with entry and exit of your nordic ski boots. The wide steering plate - 56 mm - delivers excellent stability and ski control, features that are very important when backcountry skiing under variable terrain and snow conditions. Solid platform and firm toe hold combine to offer nice turning and maneuverability in even the roughest terrain and snow type. This binding will also fit groomed nordic ski tracks. Compatible with NNN BC(using the Rottefella BC system) nordic ski boots.
