- Developed by Sean Mattison for Von Sol surfboards, the FCS VS KNUBSTER is essentially a centre fin that can be added to any quad set-up
The fin will increase drive and provide directional control through turns, without sacrificing speed, flow, or the freedom of movement typically associated with a quad.
- The “KNUBSTER” is designed with a single tab that allows the fin to be positioned in the forward and rear centre plug to cater for the individual drive requirements of each surfer.
- A wide range of conditions from beach breaks to point breaks.
- All board types.
- Will fit the FCS II Fin System when used with grub screws and the FCS Infill Kit.
