FCS II Mayhem Pivot PC Quad Rear Fin Set-Marine-Large

From FCS

Designed with shaper and pro surfer Matt Biolos, the Mayhem Pivot Quad Rears are a high-performance template for surfers seeking speed, tight turns, and quick directional changes. They suit boards ranging from elite performance models to versatile boards like the RNF and Puddle Jumper, particularly lower-rockered designs.

Part of the Reactor fin family, the upright template combines smooth curves, moderate tip area, and neutral sweep for an agile, responsive feel with sharp snaps and quick redirection.

Performance
