The Easy Rider was designed for flatter days, like those days in the summer, in between swells. The wide point is above center for more forward momentum, which is helpful in really slow surf. The bottom comes with a single concave leading into a double concave toward the tail. The wide tail block gives the surfboard plenty of drive. This model works best as a tri fin and can be ordered in epoxy foam. The Easy Rider works like a dumpster diver.
