FCS II H4 Quad Rear Fins (MED / PC Carbon / Smoke)

The H4 looks and surfs different to any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds. Quad Rears designed to work with both medium & large H4 sets. Performance Material Size Overview This set comes equipped with 2 x Quad Rear Fins, designed to work with both medium & large H4 sets. UNIQUE TEMPLATE While the science behind the template, materials & the foils are highly complex. Every component of this fin has been engineered to create a simple synergy between the fin & the surfboard, the rider & the wave. Rear Fin Synergy: The H4 quad combines the power + control of the H4 thruster, with the added speed & drive of a quad. Quad Rear Profile: A similar hybrid outline on the front and rear fins helps minimize turbulence + provides a smooth and predictable feel. Enhanced Foils: Revolutionary new foil designed to grip longer through turns and promotes perfect rail to rail transitions. Ideal Conditions A wide range of conditions, particularly good in critical overhead waves. Board Types Designed to fit the FCS II Fin System. Recommended for performance shortboards with moderate-to-low rocker. Fin Family Accelerator: Find Control. Speed, flow and response with added control. NEW CONSTRUCTION Precision Swiss Engineered: Creates perfect synergy between fin geometry & HI-FI materials, giving smooth & predictable feel. High Density Uni-Directional Carbon Fibre: Light & super strong with custom orientation to transfer more of your energy into speed than any other fin. Dynamic Trailing Edge: Internal composite morphs under extreme load, enabling the fins to be pushed harder without sliding out. Innovative Production: Highly specialized robotic automation combined with camera assisted quality control, ensures absolute accuracy.
