The FCS II Reactor PC Carbon Tri-Fin Set utilizes a superior blend of carbon tissue and an ultralight AirCore construction to deliver a more user-friendly flex to achieve faster start up acceleration, and a smoother feel through turns. These fins are designed for speed and tight turns, with added tail release. The upright template allows for tighter, more acute directional changes. A smaller center fin for increased pivot and tail release. Ideal for surfers who like to perform fast, progressive turns and suitable for hollow waves, particularly good for beach breaks.
