Overview
World Longboard Champion Harley Ingleby's Athlete Fin.
Harley's XL template delivers maximum speed and drive for powerful surfers.
Ideal for performance longboards, surf SUP's and 2+1 set-ups.
Side fins are designed to be used with the FCS II Fin System.
Performance Core
Performance Core (PC) fins are made using a multi-layered resin transfer moulding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light and can be used in a variety of different conditions.

These fins work insane in Harleys Thunderbolt longboard models.
They are definitely the best fins I have ever bought.
Harley told me to use his fin setup for the last few years in his boards. I always used a 2+1 setup because it has always worked for me in the past. I finally got these and gave them a try. My HI DD2 is now faster and looser with full control of the board. Im never changing the fins again. Im now hitting the lip at 11-12 oclock with ease and wrapping roundhouses with much more speed and control.
Quality fins, decent price. Tailor made for the HI performance longboards but perfect for any HPLB.
