The Dynafit TLT Radical FT speaks loud and clear: it is the perfect solution for ski mountaineers and freeriders who love descents. All the advantages are crystal clear: lightweight and superior performance. The carbon plate stiffens by shifting the shock absorber forward into lock. In this position the rear rubber pieces work as dampeners, and the ski stiffens up. This increases torsional rigidity between the carbon plate and binding front piece. The ski will have its natural flex characteristics in the unlock position.
