With its high durability and its awesome sliding potential, the Fat Free is a great representative of Orangatang's longboard wheels range. Not really made to ride at high speeds, the Fat Free is the perfect wheel for a playful longboard, preferably short in order to practice freestyle, street / surf style and big slides.
If you are looking for the best balance between slide's taking off and control in your turns, choose the purple one (83a hardness).
