R4 Classic is a racing binding developed specially for the NIS system. The binding slides onto the plate - already an integrated part of the ski - and the binding position may be easily adjusted in the longitudinal direction for individual skiing style.
R4 Classic is a binding perfectly suited for classic style training and racing. The R4 Classic is developed in co-operation with elite skiers who know that the binding is decisive for top performances. The binding is wide in order to achieve maximum stability and edge control. The flexors are interchangeable and available in various hardnesses to ensure finely tuned performances.
