Deflow KEEL QUAD fins – evo

Deflow Keel Quad Fins – Evo are designed to transform your surfboard’s performance by solving one of the biggest challenges surfers face with quads: turning. Many riders struggle not because of the quad concept, but due to the wrong fin setup. The Keel Quad set eliminates that problem, delivering smoother turns and improved control in a variety of conditions.

The large surface area of the front fins generates excellent drive and hold, perfect for long and powerful carves. The upright rear fins balance this out, allowing tight-radius turns and increased maneuverability. This unique blend of drive and agility makes the Keel Quad versatile across conditions: in small waves it feels skatey and playful, while in bigger surf it provides control and flow. Designed especially for wide-tailed boards, this setup enhances both speed and responsiveness.
