  • Overview

    • The MB template offers freedom to perform tight turns in the pocket with an emphasis on speed.
    • Sitting in the reactor family, the MB is considered a high performance fin because it responds incredibly fast, but still offers enough control so you can confidently lay into a turn with plenty of force.
    • Tri/Quad (5 fin) set.

    Ideal Conditions

    • A wide range of conditions, particularly good in critical overhead waves.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Performance shortboards and hybrid models.

    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.

    Versatile and responsive

    Perfect blend of drive, control, and maneuverability. Worked great as a thruster and a quad.

    Try quad fins

    Great looking fins. Smaller than I expected them to be. I’ll have to wait and see how they perform in different waves. Really impressed with the FCS II system
