Ci Upright PC Quad Rear Fins Set - FCS II - Black Flame
The FCS Ci Upright PC Quad Rear fin set - FCS II is designed for surfers who want to optimize the responsiveness and control of a quad fin setup on their performance or hybrid boards. It's ideal for riders seeking stability and precision in tight turns, while maintaining excellent drive in hollow waves or punchy beach breaks.
These rear fins, designed by Britt Merrick in collaboration with Channel Islands Surfboards, utilize a neutral-raked template and an 80/20 foil for a perfect balance between stability and maneuverability. Their lightweight and flexible Performance Core (PC) material allows for progressive flex from base to tip, providing support and grip in all types of turns and conditions. They perfectly complement the Upright CI side fins for a reliable and high-performance quad.
