Arguably the most iconic, functional and versatile single fin available...should work well in just about any board. The Greenough 4-A is one of the most popular single fin designs around - a truly well-balanced fin. The full base is coupled with a tapered & moderately flexible tip. This fin provides a solid amount of drive off the bottom and superb responsiveness through turns.

Designed for both speed generation and spending time surfing in the pocket, the 4-A is a fin that will hold when you need it to and release when the time is right. A fin that can do it all, throw one in your board and feel the success! Great in traditional longboards, noseriders single fins and 2+1 designs.
