The FCS SF4 Large Tri-Quad Fin Set is the signature shaper fin for William "Stretch" Riedel. This five fin set is perfect for a wide variety of waves, from clean steeps to choppier off beach breaks. These are performance fins that work best on boards with moderate to extreme rocker profiles

Performance Core – Performance Core (PC) material and construction is designed to deliver the feeling of a traditional fiberglass fin with the added performance of reduced weight. The RTM (Resin Transfer Moulding) process produces a lightweight fin with remarkable flex, a smooth feel and an impressive aesthetic.


  • Lively Fins with Cambered Foil Help Maintain Speed and Connect Turns
  • Ideal Conditions – A wide range of conditions, particularly good in critical overhead waves.
  • Board Types – Performance shortboards and hybrid models.
