Full Futures SB1 Side Fins

These SB1 side fins are specifically engineered as side bites for longboards or mid-lengths. They are intended to be used in conjunction with a center fin to add stability and hold, particularly when you want more control on the wave face.

These fins are compatible with the Futures fin system. Before purchasing, verify that your board is equipped with Futures boxes, as they will not fit into FCS or US Box systems.

The fiberglass construction provides a balance of durability and flex. It offers a reliable, consistent feel in the water that is generally stiffer and more predictable than plastic or composite alternatives, which helps with drive and control during turns.

A flat foil on side fins creates a clean water flow that promotes a more predictable and stable feel. It is a classic design choice that helps the board track straight and provides a secure hold when you are engaging the rail.

While they are listed as 'Quad Rears' in the layout, they are primarily designed as side bites for a 2+1 longboard setup. If you are looking to use them as rear fins for a quad setup, ensure your board's fin boxes are positioned to accommodate these specific dimensions.
