Flying Diamonds FDX1 Tri Quad 5-Fin Set Large Gray Multi-Tone - FCS Dual Tab

A five-fin set that can be run as a quad or a thruster: two separate fin setups in a single package. The FDX-1 is a balanced template with all-around performance. With a neutral template that is not overly upright or raked, it is designed to serve as the performance baseline for any shortboard or mid-length in your quiver.

Built with AirFlex technology, a precision-shaped polyurethane foam air core with high-strength fiberglass and epoxy resin, it delivers the lightest possible weight with optimal rebound under load, balancing speed, flow and response. The result is a balanced, predictable flex pattern with quick response and smooth feedback: lively through turns, stable and controlled when conditions demand it. Ideal for both creating and controlling speed as a thruster or quad.

Color: Gray Multi-Tone
