The Knubster 2-pack is a very versatile small stabilization fin. They're great for wakeboards or can tame a loose twin fin or wild quad to give that extra grip while keeping speed drag-free.

It also works excellently as a nubster for the Citywave, and thanks to the two set you also have a spare fin.

Our patented Dimple Technology, like golf balls, is proven to reduce drag by up to 15% while providing maximum control. Less air resistance on the fins gives you more speed, control, and stability in your turns. This helps you stay in the sweet spot of the wave longer.

3DFINS' unique ZGLASS formula creates high-performance wake surfing fins that are incredibly strong, durable, and provide maximum control. After trying our high-performance fins, you'll never look back.

Our eco-friendly, sustainable packaging is 100% recyclable and produced with little production waste.

Golf balls have dimples for two main reasons: a ridged surface reduces drag and improves lift. For this reason, 3DFINS has developed our patented Dimple Technology for all types of hydrofins. 3DFINS wake surfboard fins reduce air resistance, provide maximum control and stability in the turns, and, most importantly, help you maintain your speed. If you maintain your speed through the turns, you'll stay in the wave's sweet spot longer, making your ride longer and more enjoyable. You will feel the difference on your first ride. The 3DFINS wake surfing fins are perfect for every level, age, and size of surfer. Make the most of every wake size and don't let your fins hold you back.
