These fins are made of a Carbon/Basalt matrix and its shape has been developed in a watertunnel facility. Both the unique shape and the damping characteristics of the matrix contribute to the remarkable resistance to cavitation and a very low resistance in the water. Less cavitation also means that it is less prone to spin outs. These fins has everything you need in slalomracing or when trying to control your freeride board in difficult and choppy conditions. The same characteristics that give these fins their remarkable speed also makes them easier to control and manoeuvre than you thought possible for such a racy fin.
