FCS II Flow Longboard Fin

The Flow is designed for traditional, laid-back longboarding. Its neutral template and elongated base prioritize smooth, controlled turns and consistent trim stability rather than aggressive, high-performance maneuvers.

Yes, the FCS II system is designed specifically for tool-less installation. You simply insert the front of the fin into the box and press down on the back to lock it into place, which makes mid-session adjustments very quick.

The FCS II Flow is compatible with most standard longboard boxes. However, because it uses a tool-less system, it is optimized for FCS II boxes, though it will still fit and function in traditional boxes if you use the provided screw and plate.

Performance Glass is stiffer than molded plastic or composite fins. This stiffness provides a more solid, reliable feel under pressure, giving you more drive and responsiveness when you are pushing through turns.

A 50/50 foil means the fin is symmetrical on both sides, which creates a very stable, predictable ride. This is ideal for single-fin setups where you want to maintain a straight line and smooth flow without the fin feeling 'twitchy' or loose.
