The FCS GXQ Quad Rears Fin Set will have you ready to play hard when the conditions call for the quick orchestration of a quad. 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 GX Quad Rear Fins have a 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.
