FCS II Rob Machado seaside quad fins - Twin Flow with quad control

The first signature fin design by Rob Machado for the FCS II system. Developed specifically for the Firewire seaside model, these fins combine the best of both worlds: the fluidity of a traditional twin fin with the control of a performance quad fin.

Why choose seaside quad bikes?

  • Natural flow: Semi-keel + stabilizers provide smooth glide and fluid turns.
  • Total control: Quad configuration offers drive and stability in all maneuvers.
  • Extreme versatility: Works in beach breaks, point breaks, and weaker waves.
  • FCS II System: Quick, screwless installation - click and surf.

Ideal conditions:

Wide variety of conditions, from beach breaks to point breaks. Especially effective in smaller, weaker waves, where they maximize speed and flow.

Type of board:

Designed for Firewire seaside and other higher-volume hybrid models. Compatible with the FCS II system.

Quad configuration - 4 fins

Complete set with 2 front semi-keels and 2 rear stabilizers. The perfect combination for those seeking speed, flow, and control.

Technical specifications:

  • Material: Performance glass (PG)
  • System: FCS II (screwless)
  • Configuration: Quad set (4 fins)
  • Color: Camo

Performance glass technology:

Manufactured through mechanical cutting in layers of solid fiberglass, these fins are rigid and widely used by professional surfers because the integrity of the flex is maintained even under immense force and in the most extreme conditions. They guarantee consistent response and superior durability.

Surf like Rob Machado - flow, style, and control on any wave!
