When meets Elias Assmuth and Mike Schneider it always worth it, because this duo is able to dictate many interesting tricks. Today it is just about Elias, who asks a mysterious marble mini park modeled in a basement somewhere on the window. What is it? Nothing too interesting, just one grind at the window, simple concrete wave and the two times radius on the both sides. For having fun it is certainly enough. Pity that the conditions to shoot more are so miserable, because the camera is almost no where to put. But Mike knows how to do it and brought video to us after all. Look at that!
