RIDE NUMBER DESCRIBES THE FEELING OF A FIN:

This feeling is represented on a scale from Speed Generating to Speed Control. The closer you get to 10, the more springy, fluid & responsive your board will feel to help generate speed. The closer you get to 1, the more solid, engaged & predictable your board will feel to help control speed. Fins with a Ride Number around 5 feel balanced & do not add any premium feelings to your board - they let your board’s original character shine. To use Ride Number just pick a feeling in your weight range, and give it a try. When you understand the different feels, you can get the most performance & enjoyment out of your equipment.
