Designed for groms, the FCS G1000 fin is a good all-round template for lightweight riders with a soft, forgiving flex pattern. The G1000 is a small upright fin for boards up to 5`10". The small base allows for tight and snappy turns with the freedom young surfers need to develop their moves. Glass Flex is formulated to replicate the flex and memory properties of laminated fiberglass. Offers the flex pattern modeled of a hand-foiled fiberglass fin and the ability to mold highly technical computer generated foils accurately.
