This is a five-fin set that can be run as a quad (pictured) or thruster. Two separate fin setups in a single package. The Flying Diamonds FDX-1 Single Tab Tri-Quad Fin Set is a balanced template with all-around performance. With a neutral template that is not overly upright or raked, it’s specifically designed to act as a single fin set that can serve as the performance baseline for any shortboard or mid-length in your quiver.
