Thats cause noone has them yet, or very few. They are like the 916 except lighter of course. Solly says made for the park peeps that need a high din binding, but not the weight of it. Like I mentioned its a 916 with plastic toe wings and heel piece I believe. It also has the new heel track that theyre also putting on their other bindings to prevent a tear out. Sound good if you want a light, high din binding.
