Kelly Slater’s signature quad set. K2.1 PC in the side and Q-1000 in the rear, exceptional performance in all conditions.
Performance Core material and construction is designed to deliver the feeling of a traditional fibreglass 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.

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. It’s designed with a single tab for the ability to move it forward and back based on drive.
Glass Flex has been formulated to replicate the flex and memory properties of hand layed fibreglass. Its advantages over other composite fin materials include stiffness, a more positive flex pattern (nice tip flex, little base flex) and remarkable flex memory. The precision of the injection moulding process ensures the highest accuracy in geometry in each fin produced.
“The Knubster will make your favourite quad set-up feel faster, smoother, and it adds a little more control”-
