FCS Fins VS Knubster Kelly Slater Quad Fin Stabiliser
Developed by Sean Mattison for Von Sol surfboards, the FCS Fins VS KNUBSTER is essentially a centre fin that can be added to any quad set-up. The fin will increase drive and provide directional control through turns without sacrificing speed, flow, or the freedom of movement typically associated with a quad. It's designed with a single tab for the ability to move it forward and back based on drive.
Glass Flex has been formulated to replicate the flex and memory properties of hand layed fibreglass. Its advantages over other composite fin materials include stiffness, a more positive flex pattern (nice tip flex, little base flex) and remarkable flex memory. The precision of the injection moulding process ensures the highest accuracy in geometry in each fin produced.
