The METRIX system was designed to offer the flexibility of a rental track with the performance of a traditional downhill binding. The system can be mounted on any flat ski, and is ideal for ski demos. Offering uncompromised energy transmission to the ski's edge, the skier gets a true sense of the ski. It's the next generation of demo binding. The METRIX system is equipped with a reinforced Full Action toe piece and SPX heel. It can be adjusted to fit boots measuring 260 mm to 360 mm in length. Compatible with all ISO 5355 A and GripWalk® ISO 23223 A adult boot soles.
