Narrow performance single fin offering minimal resistance through turns. This fin flexes further down toward the base, making the board feel lively and more responsive. Performs well in progressive longboards, single fins and bonzers. Base: 4.29" / 109mm
The FCS system (Fin Control System) was designed by Brian A. Whitty in Elanora, Australia, and patented on November 7, 1995. It can be recognized by the 2 tabs on the fins which are designed to fit into a securing plug that attaches the fin to the board.
