FCS II Matt Biolos Tri-Quad Fin Set

Design by Matt Biolos and refined by his diverse stable of elite team riders, the new high performance MB fin is an exciting addition to the range and sits comfortably in the Carver family. Featuring a wide base, curved trailing edge and a tapered tip, this fin is primarily geared for performance power surfing. The bottom half of the fin produces exceptional power and drive, allowing surfers to push hard through turns while maintain a feeling of stability in critical situations. The tip, which narrows significantly from halfway up the fin, offers the freedom and agility to turn abruptly with confidence. In contrast to Matt's original upright template (Reactor Family) that was loose and geared for tighter turns in beach breaks, the new MB template offers a balanced blend of drive, power and release that will suit more open-face waves and turns such as carves and power hacks. This fin also pairs particularly well with higher-rocker boards. PC AirCore construction offers a stiffer flex allowing surfers to harness more power and speed when pushing ultra hard through turns. The quad rear template shares a similar outline aesthetic has been designed to work seamlessly with the side fins. As a quad this set will feel very stable and smooth to turn with an underlying feeling of control. The quad set is well suited to performance and hybrid shapes.
