The Freeflex ST 16 X RD is a high performance model and optimised for racing. The Stream toe impresses with independent spring-loaded pincers and even more precise control. The RACE PRO RD heel allows a direct, aggressive power transmission, especially for the technical disciplines. The Freeflex ST 16 X RD is one of the top models of the Racing collection with a slightly reduced adjustment range. It includes the Adaptive Suspension Technology, featuring independent spring-loaded pincers, two mounting positions for an adjustable pressure point, a steel base plate for more direct power transmission and a 5 mm lower contact point between the binding and the boot for an even lower impact on the ski's natural flex. Like all X bindings, the Freeflex ST 16 X RD binding has a race-optimised release characteristic and a spindle adjustment to accommodate forward pressure in order to guarantee the most precise adjustment and the best performance. In order to withstand the heavy strains involved in racing, some parts are made of aluminium. This ensures maximum stability, durability and the best energy transfer.
