The NEOX+ 412 ski binding is compatible with all Atomic skis with mounting plates and all non Atomic 'flat' skis or universal plate systems. With a DIN range from 4 - 12 this binding will work well for the 80 - 250 lbs. weight range. The FULLFLEX TWIN system uses one central mounting screw and free-gliding toe-and heel pieces providing tension-free connection between boot and ski. You will find improved edge contact for precise ski control and 100% displacement of energy for tenacious edge grip. The NEOX+ 412 provides greater safety through constant forward pressure and exact and backward release.
