FCS II Reactor PC Tri Fins

Designed for speed and tight turns, the FCS II Reactor PC Tri Fins deliver responsive performance across a range of conditions. The upright template enables acute directional changes, while the smaller centre fin increases pivot and tail release for progressive manoeuvres. Built with Performance Core (PC) technology, these fins feature a multi-layered resin transfer moulding process that creates a progressive flex pattern from base to tip. This maintains drive and hold through turns whilst keeping weight minimal. Ideal for hollow waves and beach breaks, these fins suit performance shortboards with moderate-to-low rocker. Available in five sizes to match your weight range, from X-Small (under 55kg) to X-Large (over 85kg). Compatible with the FCS II Fin System. Perfect for surfers seeking fast, snappy turns and dynamic control.

Performance Core

Performance Core (PC) fins are made using a multi-layered resin transfer moulding process.
