Biolos Pivot Performance Core Carbon Quad Rear Medium

Designed in collaboration with shaper and pro surfer Matt Biolos, the Mayhem Pivot Quad Rears are a refined high-performance template built for surfers who want speed, tight turns, and quick directional changes. Suitable for a wide range of boards—from elite high-performance models to versatile everyday boards like the RNF and Puddle Jumper—this fin emphasizes agility and responsiveness, particularly on lower-rockered boards.

Part of the Reactor fin family, the Mayhem Pivot features smooth curves, a moderate tip area, and a neutral sweep angle, delivering a smooth feel while allowing for sharp snaps off the top and rapid turn redirection. Inspired by the Reactor template, it is designed for beach break conditions where speed and acute turning are essential.

The stealthy new aesthetic completes the signature design, pairing performance with style for surfers seeking a responsive, speed-oriented fin.

• Designed in collaboration with Matt Biolos
• Upright template for tight turns and quick directional changes
• Moderate tip area and neutral sweep for smooth, responsive feel
• Built for speed, snaps, and tail release
• Ideal for beach breaks and lower-rockered performance boards

The Mayhem Pivot provides fast, responsive, and agile performance.

The upright template allows surfers to perform tight, acute turns with confidence, while the smooth curves and moderate tip ensure stability and control during high-speed maneuvers. This fin excels at generating drive through the pocket and quick redirection off the top, making it ideal for surfers who like to attack critical sections of the wave with speed and precision.

The result is a fin that feels lively, controlled, and highly responsive, perfect for performance-focused beach break sessions.

Built for speed, tight turns, and explosive snaps.

The Reactor template features an upright outline with a smaller centre of area, allowing the board to pivot quickly and release cleanly off the top.

This makes it ideal fin for surfers who favor fast surfing, sharp turns, and progressive manoeuvres.

Performs particularly well in:

• Hollow waves
• Fast, punchy beach breaks
• More critical surf conditions
