FCS II Reactor Fins

These fins are designed for hollow waves and punchy beach breaks. The upright template and smaller center fin are specifically engineered to help you stay in the pocket and make quick, tight turns in steeper sections.

The AirCore construction uses a lightweight foam core, which significantly reduces the weight of the fin compared to solid fiberglass. This makes the board feel more responsive and lively under your feet, allowing for faster acceleration and easier transitions between turns.

The smaller center fin is a deliberate design choice to increase pivot and tail release. It allows the board to turn more freely and sharply, which is essential for performance surfing where you need to make acute adjustments in the wave's critical zone.

These fins use the FCS II system, which is designed for tool-less installation and removal. They are compatible with any surfboard equipped with FCS II fin boxes, though they are optimized for performance shortboards rather than longboards or retro shapes.

The carbon tissue adds a specific stiffness to the fin that creates a snappy, responsive flex. It ensures the fin loads up energy during a turn and releases it quickly, giving you a predictable and controlled feel when you are pushing hard through maneuvers.
