Collection: FCS II REACTOR FAMILY
The Reactor fins feature a low rake design, making them upright and ideal for quick reactions and tight-radius turns. This shape facilitates fast, agile maneuvering, especially in hollow waves, but sacrifices some hold, making them less suitable for power surfing. Reactor fins work best with boards that have low rockers, enhancing performance for surfers who prefer responsive turns.
