FCS MR-TFX Twin + Stabilizer

This setup is designed primarily for fish, hybrid shapes, and funboards. The twin-plus-stabilizer configuration adds the necessary control to these wider-tailed boards without sacrificing the loose, fast feel that makes them fun to ride.

The stabilizer acts as a pivot point, providing a bit more hold and predictability during turns. It prevents the board from sliding out too easily, giving you more confidence when pushing through carves while still maintaining the speed of a twin fin.

No, these are FCS I fins. While they can be installed in FCS II boxes using the appropriate grub screws, they are designed for the original FCS dual-tab system and do not feature the tool-less click-in mechanism of the newer FCS II standard.

Performance Core construction uses a resin transfer molding process to create a consistent, progressive flex pattern. This means the fin bends predictably under pressure, helping you maintain drive and energy through your turns from the base all the way to the tip.

While these fins excel in small to medium conditions, the added stabilizer makes them more versatile than a pure twin setup. You can certainly take them into punchier waves, but they are generally optimized for performance in average, everyday surf.
