This FCS GX Glass Flex surfboard side fin set are high performance traditional longboard side bites (two rear fins) designed to add speed, stability and control. Suitable for use in longboards, SUP's or as quad rears.
A wide range of conditions from beach breaks to point breaks.
All board types including mid-lengths, Longboards and SUP's.
Injection moulding process ensures geometric accuracy and provides a reliable and consistent feel. These fins are ideal for novice surfers because the relaxed (subtle) flex of these fins can be engaged with minimal effort, and as the flex returns to a neutral position the fin produces a whip-like effect that propels the board forward, and helps to maintain speed and acceleration.
