The first 16-DIN tech binding, the new Beast features a “return to center” toe piece. As you ski, the binding deflects to absorb shock. It’s one of the reasons, safety-wise, alpine-style bindings outperform tech bindings.
You now have two choices when it comes to telemark bindings: 75mm (traditional duckbill) and the newer NTN. The former is favored for its simplicity, lower cost, and greater variety of boot choices, but NTN is vastly more powerful and releasable, and it’s better-suited to driving today’s fattest skis.
Dynafit-style tech bindings, like the Radical and the La Sportiva RT, are the only ones that offer a true free pivot, meaning there’s no hardware attached to your boot heel or sole. They have fewer moving parts, ice up less, and require 15 percent less energy from you than other bindings.
