FCS II Firewire Fins

The Performance Core Carbon (PCC) construction uses a carbon tissue insert instead of bamboo. This creates a more responsive, controlled flex pattern that feels snappier and more predictable when you are pushing hard through turns.

No, these are FCS II fins designed specifically for the tool-less FCS II system. While they are backward compatible with older dual-tab boxes if you use grub screws, they are optimized for the click-in, click-out convenience of the newer system.

The smaller center fin is a deliberate design choice to reduce surface area in the tail. This allows for easier, faster tail release, which helps you break traction more readily when performing explosive maneuvers.

These fins are specifically engineered for critical, overhead conditions where you need maximum stability and hold. While they can be used in smaller surf, you might find them a bit stiff or 'tracky' if the waves lack the power to engage the deep side fins properly.

This set pairs best with high-volume shortboards and performance-oriented hybrid models. They are designed to provide the drive and hold needed for boards that are being ridden in punchy, powerful surf.
