FCS II Mayhem Pivot PC Carbon Quad Rear Fins | Quad Speed with a Pivot Feel
Swap your centre fin for these rears and feel the Pivot template loosen up. Matt "Mayhem" Biolos' upright outline carries into a quad setup that's fast, free and quick to whip under the lip — all the vertical intent of the Pivot tri set with the extra down-the-line speed only a quad delivers. Finished in Sand to match the Pivot tri fronts.
Key Technical Features
- Matt "Mayhem" Biolos template: Designed with the Lost Surfboards mastermind whose boards and fins sit under the world's best surfers.
- Pivot rear template: Scaled to pair with the Pivot front fins — tight-arc redirection with the speed and release of a quad setup.
- Performance Core Carbon (PCC): FCS's fastest-responding construction — a carbon tissue inlay delivers uniform base-to-tip flex and instant energy return.
- Quad rear set: Two rear fins with 80/20 foils for speed, hold and clean water flow between the fins.
- FCS II System: Keyless, tool-free install — click straight into your FCS II plugs and paddle out.
