FCS II Performer fins are designed to be the go to fins for most conditions. They give a great balance of speed, flow, turning and response. These are size Medium for riders of 65-80kg and have the glass flex core. Fins have a width of 111mm at the widest point and 115mm high, the rake on these is 33.7 degrees and they have an inside foil.
The FCS II fins are the latest offering from FCS. They don't need allen keys anymore as the fin boxes are equipped with a quick release spring pin. The advantage of these over the FCS I? If they do hit the bottom it does break the fin out and not the whole fin box.
NOTE-The board must be fitted with FCS II fin boxes for these fins to fit.
