Built for surfers chasing a fast, controlled quad setup, these rear fins are tuned to deliver a strong balance of maneuverability and directional control in more performance-oriented surf. :contentReference[oaicite:0]{index=0}\u003c\/p\u003e\r\n\r\n  \u003cp\u003eThe defining feature here is the 50\/50 foil, which promotes smooth, longer-arc turns while maintaining exceptional stability, especially when the board is locked into the barrel. That makes this rear set a great choice for surfers who want the speed and drive of a quad without losing the hold and predictability needed in steeper, more powerful waves. FCS places this set in the Carver family, built for powerful, drawn-out turns with added hold. :contentReference[oaicite:1]{index=1}\u003c\/p\u003e\r\n\r\n  \u003cp\u003eConstructed in Performance Core, these fins use a multi-layered resin transfer molding process with a flex pattern that extends progressively from base to tip. FCS says this helps maintain drive and hold through a turn while keeping the set light and versatile across conditions. In Medium, FCS lists the rider range at 145 to 175 pounds. :contentReference[oaicite:2]{index=2}\u003c\/p\u003e\r\n\r\n  \u003ch3\u003eWhy You'll Love It\u003c\/h3\u003e\r\n  \u003cul\u003e\r\n    \u003cli\u003eDesigned by Al Merrick to match the raked AM side fins\u003c\/li\u003e\r\n    \u003cli\u003e50\/50 foil adds smooth turning and excellent barrel stability\u003c\/li\u003e\r\n    \u003cli\u003eGreat balance of maneuverability and directional control\u003c\/li\u003e\r\n    \u003cli\u003eIdeal for hollow, steep waves and punchy beach breaks\u003c\/li\u003e\r\n    \u003cli\u003ePerformance Core construction offers light weight and versatile flex\u003c\/li\u003e\r\n    \u003cli\u003ePerfect rear set for a fast, controlled performance quad\u003c\/li\u003e\r\n  \u003c\/ul\u003e\r\n\r\n  \u003ch3\u003eFeatures\u003c\/h3\u003e\r\n  \u003cul\u003e\r\n    \u003cli\u003eModel: FCS II Al Merrick Quad Rear Fin Set\u003c\/li\u003e\r\n    \u003cli\u003eSize: Medium\u003c\/li\u003e\r\n    \u003cli\u003eConstruction: Performance Core\u003c\/li\u003e\r\n    \u003cli\u003eFin System: FCS II\u003c\/li\u003e\r\n    \u003cli\u003eFoil: 50\/50\u003c\/li\u003e\r\n    \u003cli\u003eFin Family: Carver\u003c\/li\u003e\r\n    \u003cli\u003eConfiguration: Quad Rear (2 fins)\u003c\/li\u003e\r\n    \u003cli\u003eSuggested Rider Weight: 145 - 175 lbs\u003c\/li\u003e\r\n    \u003cli\u003eBest For: Performance boards with deep concaves and moderate-to-extreme rocker\u003c\/li\u003e\r\n  \u003c\/ul\u003e\r\n\r\n  \u003cp\u003eWhen you shop at Rider Shack, you’re supporting a small business and core surf shop run by surfers who care about quality gear, real surf knowledge, and genuine customer service.\u003c\/p\u003e\r\n\u003c\/div\u003e","brand":"FCS","offers":[{"title":"Default Title","offer_id":52368844292379,"sku":"118977","price":92.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/6868\/9435\/files\/118977.jpg?v=1781734525","url":"https:\/\/www.ridershack.com\/products\/fcs-ii-am-pc-md-quad-rears","provider":"Rider Shack","version":"1.0","type":"link"}
