The Circle One Surf Quad Set is an excellent choice for surfers looking to improve their board's responsiveness and stability in various wave conditions. Designed for intermediate to advanced riders, these honeycomb fins offer a lightweight yet durable construction that excels at maintaining speed through turns. While the quad configuration provides superior drive and hold compared to standard thrusters, riders should note that they require specific attention to fin box compatibility to ensure a secure fit for optimal performance.

These fins are designed for boards equipped with FCS or FCS Fusion fin boxes. Please verify your board has these specific systems before purchase.
The honeycomb core makes the fins significantly lighter than solid plastic or fiberglass, allowing for better board response without losing necessary stiffness.
Typically, the necessary grub screws are provided with the fin box system on your board; always ensure you have the correct key to tighten them.
While they can be used by anyone, they are primarily designed for intermediate surfers looking to dial in specific performance characteristics like speed and drive.
Store them in a cool, dry place away from direct sunlight when not in use to prevent material degradation.
Check the box for accumulated sand or salt. Clean the cavity thoroughly with a small brush or fresh water.
Ensure the grub screws are fully tightened. If the screw is slipping, check if the screw head or the internal thread in the box is damaged.
These fins are designed for standard FCS and FCS Fusion systems. To install, ensure the fin box is free of sand or debris before inserting the fin base. Press the fin firmly into the box until it seats flush against the board surface. Tighten the grub screws gently—do not overtighten, as this can strip the threads or damage the fin base.
After every surf session, rinse the fins and fin boxes with fresh water to prevent salt buildup, which can make future removal difficult. Inspect the fin edges periodically for nicks or deep scratches; if any occur, lightly sand them down with fine-grit sandpaper to keep the hydrodynamics optimal.
