Futures Thermo SB1 Sidebite

The SB1 sidebites are specifically engineered for longboards and 2+1 fin configurations. They are intended to complement a larger center fin by adding stability and hold without sacrificing the maneuverability of your board.

Unlike standard composite or plastic fins that can feel stiff or dead, Thermotech is designed to provide a more consistent flex pattern. This allows the fin to load up and release energy through turns, giving you a more responsive and lively feel on the wave.

The truss base is a structural feature that removes unnecessary material from the fin's base. This effectively reduces the overall weight of the fin while maintaining the necessary strength and rigidity for high-performance surfing.

No, these are designed specifically for the Futures fin system. They will not fit into FCS or other proprietary fin box setups.

A flat foil is generally more predictable and provides a clean, consistent water flow. It is a great choice for sidebites because it offers a reliable hold and quick response, making it easier to initiate turns.
