2026 FCS II Harley Ingleby HIBT Twin Fin Set | Maximum Drive and Versatility
Unlock the full potential of your hybrid or performance shape with the FCS II Harley Ingleby HIBT Twin Fin Set. Designed to capture that iconic Aussie blend of speed and freedom, these fins aren't just about cruising; they’re about pushing your rail into the water with total confidence. Whether you’re chasing long points or punchy beachies, this set provides the raw power of a twinny without the "skating-out" feel, giving you a ride that is as responsive as it is fast.
Key Technical Features
-
Highest Surface Area in FCS Range: As Harley’s largest twin set, these allow you to lean harder into your carves and push through turns without losing your line.
-
Moderate Sweep & Full Tip: The generous rake and elongated base deliver incredible drive and down-the-line speed, perfect for clearing flat sections.
-
Low Depth Profile: By keeping the depth shallow, the fins maintain a sense of manoeuvrability and looseness, ensuring you can still pivot sharply off the top.
-
HIBT 3+3 Compatibility: Specifically engineered to integrate with the HIBT 3+3 model. When paired with the HIBT Quad set (sold separately), you can run these as a true twin, a quad, or a creative asymmetrical setup.
-
FCS II Tool-less Tech: Snap them in and head out; no screws or keys required to find your flow.
Why You’ll Love It
If you’re a surfer who loves the speed of a twin fin but hates feeling "washy" in bigger sets, this is your new go-to. It’s essentially a performance upgrade for your fish, funboard, or hybrid, offering a "three-boards-in-one" versatility when combined with the quad rear. It’s for the rider who wants to experiment with their lines while maintaining the expert-level drive that Harley Ingleby demands.
