FCS II Matt Biolos Fin Set

These fins are built for power surfing. The wide base and stiff flex are specifically engineered to help you generate drive and maintain speed through hard, aggressive turns on open-face waves.

Yes, this is a versatile five-fin set. You can configure them as a thruster for a more traditional, pivot-oriented feel, or as a quad setup if you want more speed and hold down the line.

The stiff flex minimizes energy loss, meaning more of the power you put into your turns is transferred directly into speed. It is ideal for surfers who want a responsive, predictable feel when pushing hard through maneuvers.

These fins use the FCS II system, which is designed for tool-less installation on FCS II boxes. They are best suited for performance shortboards and hybrid models, particularly when you are surfing waves with open faces.

The Matt Biolos template is designed for surfers up to 200 lbs. If you are significantly above this weight, you may find the fins feel too loose or lack the necessary drive.

While the wide base provides the drive, the tapered tip allows for easier release. This combination gives you the stability you need to carve hard, but still allows for the agility required to snap or turn abruptly.
