Futures SB1 Side Byte Fin

These fins are specifically designed for the Futures fin system. They will only fit into side-bite boxes that are Futures-compatible, not standard US box or FCS systems.

Adding these side bites adds extra hold and stability, particularly in steeper or faster waves. They provide more drive and control through your turns, making the board feel more responsive without completely losing the classic, loose feel of a single-fin setup.

While they are optimized for longboards, they can be used on any surfboard equipped with Futures side-bite boxes. They are commonly used on mid-lengths or 2+1 setups to add stability and tracking.

You don't necessarily have to, but many riders find that switching to a slightly smaller or more upright center fin helps balance the increased hold provided by the side bites. It is worth experimenting with your center fin size to find the setup that best suits your riding style.

Yes, the SB1 Side Byte fins come as a set of two, which is the standard configuration for adding side bites to a 2+1 longboard setup.
