モデル解説
This board is not designed for professionals or teams.
This is a completely new model that was researched and developed in collaboration with Matt Biolos, also known as Mayhem, who was ranked number one in the world as the WSL World Number One Shaper in 2023, and has been specially shaped and designed as a Japan-exclusive model.
This model was conceived by Nishii and developed in collaboration with Mayhem for average Japanese users like you, and released as a Japan-exclusive model. Nishii requested Mayhem to come up with a shape design concept in late 2021, and through repeated behind-the-scenes testing and error, the design was completed in 2024. It is the ultimate wave magnet machine.
It was created to satisfy weekend surfers like you who can't surf every day and can only surf one or two days a week.
Based on Mayhem's classic RNF (Round Nose Fish), this is the ultimate paddle machine. It was developed to fulfill the weekend surfer's dream of catching as many waves as possible in a short space of time.
The large body allows for easy maneuverability on the water surface. The bottom concave (single, double, vee) adjusts the water flow and converts it into speed , the round rails change shape from nose to tail, and the bottom has a beautiful rocker curve and volume balance that was tested many times by Mayhem and Nishii to perfect it.

The DURA-FLEX structure that Presebo surfboards boast provides you with more than just paddle speed, with flexibility that fits the waves and makes it easier to ride, and spring back for speed acceleration.
The classic round nose fish template from Lost surfboards has been resized and finished with MAYHEM's signature round tail, and the shape is designed with an emphasis on ease of paddling, speed, and ease of riding.
Nishii is 5'4" and Mayhem is 6'8", and both like to use the MAYHEM 5 fin set with QUAD fins. This model is designed for busy weekend surfers who want to enjoy surfing to the fullest.
Updated to DURA-FLEX5!
This fast-paced board not only resists discoloration from the sun, but also boasts strength and durability far exceeding that of polyboards, making it even more durable and impact-resistant than its price suggests!
DURA-FLEX5 is an original, eco-friendly, long-life technology that only we at PLACEBO Factory can manufacture. The core of this new composite surfboard, which provides the incredible long-lasting durability and semi-permanent sun-resistant finish that's characteristic of the PLACEBO brand, is lightweight, high-density EPS foam called AEROBLANK. This AEROBLANK EPS foam is machine-cut and hand-custom-shaped at the PLACEBO Factory, then carefully hand-glassed with epoxy resin, three layers of 4+4+6oz cloth for the deck and two layers of 4+6oz cloth for the bottom. The board is then finished with a UV-blocking matte white paint, creating the MAYHEM shape design.
Both sides of the board are built with the Rhombus Carbon Stringer technology inherited from PLACEBO's top-of-the-line model, FLEXLITE-ULTIMATE6.
The board features a rhombus carbon stringer with a diamond-shaped trim that widens the carbon fiber at the nose tip from 1mm to a maximum width of 2.5mm at 52.5cm, resulting in a tail-end carbon fiber width of 1mm, providing a solid ride. The rhombus carbon stringer uses slightly wider carbon fiber in the nose area to stiffen the flex, minimizing flex and pushing the nose forward, translating into speed. The carbon fiber width tapers from the widest point toward the tail area, providing a softer flex and improving response. The newly developed "DURA-FLEX5" technology allows riders to achieve greater speed and control the board with agility.
The UV-cut matte white paint applied to the entire deck, bottom, rails, etc. is a long-lasting eco-finish that semi-permanently prevents discoloration from the sun. The elegant finish with carbon stringers and the black and matte white body design are equipped with the flex performance unique to PLACEBO surfboards, designed with the utmost importance on riding the waves, making them "supple and easy to ride."
