FCS II Matt Biolos PC Carbon Fin

This fin set is built for power surfers who prioritize speed and aggressive, tight turns in the pocket. It belongs to the Reactor family, meaning it’s designed to help you make quick, responsive maneuvers in critical sections of the wave.

These fins are designed specifically for the FCS II fin system, which allows for tool-less installation. Please ensure your surfboard is equipped with FCS II boxes before purchasing.

The Performance Core Carbon construction adds stiffness and a snappy, explosive response compared to standard fiberglass or basic plastic fins. This extra rigidity helps the fin maintain its shape during high-force turns, giving you more control and drive in overhead conditions.

The sizes correspond to the rider's weight and the amount of surface area needed for optimal performance. Generally, smaller fins provide more maneuverability for lighter surfers, while larger fins offer more hold and drive for heavier surfers or larger boards.

A flat foil provides a consistent, reliable feel that is predictable in a wide range of conditions. It is a standard choice for thruster setups, offering a balance between speed and control without the added lift or drag of more complex foil shapes.
