I'm selling these because I got new fins. [Discontinued Color] The legendary fin, the most highly-regarded in FCS2 fin history. Beautiful condition with few scratches (details below). [Description] FCS2 AM Large Honeycomb Core M Size ■Side Fins Base: 116mm Height: 115mm ■Center Fin Base: 110mm Height: 112mm The AM honeycomb core red/black is the most highly-regarded M-size fin in FCS2 history, praised by many YouTubers and professional surfers. It has superior flex performance compared to the conventional small honeycomb core. The AM series, designed by Al Merrick, has been a long-running hit, supported by surfers around the world for many years. To improve maneuverability, the center fin is slightly smaller than the side fins, achieving a perfect balance of turning and acceleration. The honeycomb core structure allows the resin in the foam gaps to act as supports, realizing a flexible flex characteristic. It pursues lightness and dramatically lightens the feeling in the tail area. Thank you.
