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.
Will fit the FCS II Fin System when used with grub screws and the FCS Infill Kit.
WASHING INSTRUCTIONS:
Machine wash separately in cold water on a gentle cycle. Tumble dry separately on low heat. Add QE Home Wool Dryer
Balls to reduce wrinkles and increases drying efficiency. Touch up with a low heat iron as needed. Do not bleach or dry clean.
