FCS FCS II Mayhem Pivot Performance Core Carbon Quad Rear Fins

FCS II Mayhem Pivot Performance Core Carbon Quad Rear Fins

Complete your quad setup with the FCS II Mayhem Pivot Performance Core Carbon Quad Rear fins. These rear fins were designed in collaboration with shaper Matt 'Mayhem' Biolos of Lost Surfboards. The fins belong to the Reactor family, meaning they are built for speed, sharp turns, and smooth direction changes. Whether you screw them onto a performance shortboard or a board with a lower rocker (such as the RNF or Puddle Jumper), these quad rears instantly give your board a responsive and maneuverable character.

The fins are built from the rigid Performance Core Carbon (PCC) construction. The carbon weave runs through the entire template and provides extra stiffness towards the tip. This translates into immediate feedback in the water, a fast rebound, and reliable control when surfing critical sections. The upright design with a neutral sweep and moderate tip ensures a smooth release from the tail. These characteristics come into their own in punchy beachbreaks and hollow waves, where responsiveness and tight surfing in the pocket are important.
