  • Overview


    The new PC Carbon Essential Series utilises a superior blend of carbon tissue and our ultralight AirCore construction to deliver a more user-friendly flex to achieve faster start up acceleration, and a smoother feel through turns.

    • Designed for speed and tight turns, with added tail release.
    • Upright template allows for tighter, more acute directional changes.
    • Smaller centre fin for increased pivot and tail release.
    • Ideal for surfers who like to perform fast, progressive turns.

    Ideal Conditions

    • Suitable for hollow waves, particularly good for beach breaks.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Recommended for performance shortboards with moderate-to-low rocker.

    Fin Family

    • Reactor: Find Speed. Speed, tight turns & snaps.


    • Performance Core Carbon

      Often referred to as PC Carbon or PCC, these fins are highly responsive and feature strategically placed carbon that’s designed to complement the fin template. PCC fins suit fast surfing and are favored by power surfers who like to perform explosive turns on critical parts of the wave.

      The new PCC Essential Series fins have been constructed using AirCore technology, which is a pressed polyurethane foam core that mimics the geometric foil of the fin. With AirCore we can make a much lighter fin with total manipulation of the flex.

      The internal carbon framework is designed specifically to suit each template, and by switching to epoxy resin and adding a carbon twill to the base we’ve delivered a more user-friendly flex pattern. Stiffness in the lower half of the fin enhances drive and acceleration from take-off, and a softer flex through the top half of the fin results in a smoother and more predictable feel when turning.

      Reactor PC Carbon Reaction

      I was super pumped that my FCS II Reactor PC Carbon Fins arrived before Hurricane Dorian swell arrived here in New Jersey. These fins performed as advertised, and I had a stellar session in epic east coast conditions. As a comparison, I think I prefer the Performer fins for all around conditions, but the Reactor set might be my go to for punchy, steeper surf.

      Nice!!! As described

      I purchased these hoping to get more of a loose feeling on my puddle jumper board. They delivered as promised. Can’t wait to try them on other boards I have. I recommend.

      There is a fair bit of science behind these fins. This is my third set. They all perform a little differently in various conditions. Can't wait to see how this new set of fins perform on my next surf trip.
