If your board has five fin plugs, the FCS Fins GXQ Medium Quad Rears Fin Set will add some spice into your three fin life. With the ability to be paired with the side fins out of your tri set, these two-speed generating appendages offer the drive typically associated with a quad, while maintaining maneuverability and tail release. The FCS GXQ Quad Rear Fins have an 80/20 foil and a tapered narrow tip for incredible control in hollow steep waves and punchy beach breaks. The performance core construction creates an extended flex pattern that progresses through from base to tip making it easier to maintain power and hold through turns. An easy way to add some variety to your current fin setup, the FCS GXQ Fins offer a balance of speed, flow, and response in an extremely versatile template.
