FCS II Reactor Performance Core Fin

The Reactor template is designed for surfers who prioritize speed and tight, responsive turns. It excels in the pocket of the wave and is particularly well-suited for aerial maneuvers where quick reaction times are necessary.

No, these are FCS II fins, which are designed for the tool-less FCS II system. While they are backward compatible with older FCS dual-plug systems if you use grub screws, they are specifically engineered to click in and out without tools in FCS II boxes.

Performance Core construction balances a lightweight feel with a responsive flex pattern. This gives you a lively, snappy sensation through turns, providing the hold you need without feeling overly stiff or rigid.

These fins are generally geared toward intermediate to advanced surfers looking for high-performance agility. Beginners often benefit from a more neutral, stable fin template rather than the quick, reactive nature of the Reactor.

FCS size Small fins are typically recommended for surfers weighing between 120 lbs and 155 lbs (55 kg to 70 kg). Choosing the right size is crucial for ensuring the fins provide the correct amount of drive and hold for your specific body weight.
