True Ames Greenough 4C Fin

The Greenough 4-C is a high-aspect single fin designed for longboards, based on early 1970s templates by George Greenough. Developed as a step away from traditional pivot fins, it features a semi-pivot outline with reduced surface area for less drag and improved maneuverability. The upright profile maintains hold through turns while allowing faster down-the-line speed. Compatible with a range of longboard styles, including progressive and transitional shapes. Constructed from solid fiberglass with a flat matte finish.
