The Dynamique has proven itself as the ultimate bi ski and bridges the gap between the Bi-Unique and mono skis. Skiers and instructors alike are enjoying the unparalleled design of the Dynamique. An unprecedented load height, unique tension-ed load system, and performance suspension are just a few of the features that make the Dynamique an unbounded bi ski! The Bi-Unique is used by almost every adaptive program around the world. It has set the standard for introductory sit skis and gives you the ability to ski as independently as your experience and abilities allow!
