Material:
Performance Core Carbon (PCC) combines the proven Performance Core construction with full-template carbon tissue reinforcement. Built using a multi-layered RTM process with a lightweight hex core, this trusted construction delivers progressive flex, drive and reliable performance across a wide range of conditions. Extending the carbon tissue across the full template adds controlled stiffness, particularly through the tip, complementing the fin’s more upright outline with faster rebound, sharper response and more positive feedback through tight turns and rapid direction changes.
