Quad concave bodyboards are boards with 4, 5, or even 6 channels on the slick of the bodyboard, providing extra grip on the wave face and a slight speed boost when approaching the wave lip or riding long walls.
Regardless of that, quad concave bodyboards can be made from any material, but they are typically crafted from PP or NRG as they are high-quality bodyboards.
A quad concave bodyboard provides excellent wave face grip, ideal for vertical take offs and aggressive maneuvers. Its four well-defined channels increase speed and improve control on powerful waves, allowing riders to project toward the wave lip with greater stability. Perfect for intermediate and advanced riders seeking optimal performance on all types of waves.
The classic quad concave has four deep and pronounced channels starting at the middle of the board, providing maximum grip and superior control. The mini-quad has shorter and shallower channels, offering a balance between speed and maneuverability. This makes the board looser and more agile, facilitating quick turns and smooth transitions.
SDC+ stands for Single to Double Concave Plus and is designed to optimize control on powerful waves. It combines a single concave evolving into a double concave towards the tail, with a 2mm deep rail concave that improves water flow, stability, and control without sacrificing speed. The RRC (Rail to Rail Concave) is a true quad channel with longer side channels and a wider, deeper central channel. It provides greater speed, grip, and maximum responsiveness, ideal for advanced riders looking for aggressive maneuvers and fast rail-to-rail transitions.
The main difference between these two constructions lies in the stringer:
AlphaFlex: It does not have the traditional tubular stringer. Instead, it uses the NMD PFS‑T system, consisting of two high-density foam strips along the length of the board. This provides a more direct torsional flex and maximum overall flex, making the board react more sensitively to the rider's movements. The result is a very comfortable, playful, and maneuverable board, ideal for riders seeking fluidity and fun in their maneuvers.
Quantum PP: Combines the traditional central tubular stringer with the PFS‑T system. This gives greater stiffness and stability, especially at high speed, and a powerful response in radical maneuvers. It is more suitable for heavy, powerful waves, as the board is stiffer and heavier, providing control and projection in demanding conditions.
