Get nice sharp turns and tight lines on the FCS II Reactor PC Quad Rears Fin Set. Throw these two rear fins in and turn your Reactor Tri Fin into a speed generating quad set up. Ideal for hollow waves and punchy a-frames, these upright fins create tight turning and quick tail release. Performance Core construction delivers a stiff and responsive fin that is incredibly lightweight. Particularly good for beach breaks, Reactor fins are ideal for surfers who like to perform fast, progressive turns and work best in shortboards with moderate-to-low rocker.


Performance Core construction features an updated large hex core that reduces weight, resulting in a lighter and more responsive fin. The stiff flex pattern extends progressively from the base through to the tip helping the surfer to maintain drive and hold through a turn. PC fins are reliable, very responsive, and can be used in a variety of different conditions.
