FCS MR-TFX Twin + Stabilizer

The small stabilizer fin acts as a pivot point, providing extra control and hold through turns without sacrificing the loose, fast feeling that makes twin-fin surfing so enjoyable.

These fins are designed for the FCS I fin system. They are best suited for fish, funboards, and dedicated twin-fin boards that utilize that specific box configuration.

The multi-layered resin transfer molding creates a progressive flex pattern. This means the fin is stiffer at the base for drive and speed, but flexes more toward the tip to help you maintain control during turns.

Because of the Mark Richards template, this set excels in a wide range of conditions. It provides the speed needed to generate momentum in smaller, weaker waves, while the stabilizer offers enough security to handle steeper, more powerful sections.

Compared to a thruster, this twin-plus-stabilizer setup will feel significantly faster and looser. You get the speed of a twin-fin with just enough extra stability to prevent the board from sliding out during aggressive maneuvers.
