The binding was introduced around 2013, i.e. before the Dynafit patent expired. This means that it differs significantly from the patent by definition. I already noticed the binding back then. The problem was that the binding also required a special boot. Not every common model with a Dynafit heel mount is compatible with this binding. It was only last winter that I stumbled across the binding again, as a friend from Livigno had had it fitted to his skis for some time. He was really convinced by the binding.
Now Ski Trab offers a bracket for the heel part of the ski boot, similar to a Dynafit Beast. Nevertheless, it still needs additional recesses in the plastic. As one of these bindings was on sale with a good discount, I wanted to take the opportunity to test the design myself. As it turned out, the heel bar was still relatively new and therefore not yet available everywhere. I was therefore forced to make a trip to Livigno to make the necessary adjustments to the shoe. It also turned out that the heel piece is only compatible with the newer models of the Ski Trab TR2 binding. In the end, everything turned out fine and I was able to fit the binding to the ski.
