Surf System Compatibles FCS 1 Fins Side GX

Surf System Compatibles FCS 1 Fins Side GX

Control, grip, and responsiveness to boost your 2+1 or Quad setup

Bring an extra dose of drive and hold to your board with this set of two FCS 1 compatible side fins in the GX Black template.

Designed for surfers looking to optimize their board's performance without locking up its pivot, these side bite fins deliver an ideal balance between stability and responsiveness. Whether you're rigging up a longboard or single fin in a 2+1 setup, fine-tuning a mid-length, or completing a Quad set as rear fins, the GX template is a reliable choice that locks in your turns and provides extra drive out of maneuvers.

Technical Features & Performance

• Specific GX Template: An intermediate profile offering more sweep (rake angle) than a classic GL model, ideal for adding extra hold and rail-to-rail control.

• FCS 1 System Compatibility: Features traditional dual-tab bases to fit seamlessly into all FCS 1 plug systems (also compatible with FCS II boxes using Infill Kits and grub screws).

• Foil Profile: Engineered for placement on outer rails to channel water flow, generate speed, and prevent sliding out during hard carves.

• Durable & Lightweight Construction: Robust composite material built to withstand mechanical stress, minor sand bumps, and wear from UV rays and saltwater.

• Sleek Black Finish: Clean matte black finish that pairs elegantly with any board design and glass color.

Key Highlights

• Multi-Board Versatility: Perfect as side bites on a longboard or egg, but equally effective as quad rear fins on a shortboard or fish setup.

• Reassuring Hold: Thanks to its 100 mm depth and refined rake angle, the GX shape holds firmly to the wave face during committed bottom turns.

• Quick Installation: Simple, reliable mounting using standard dual grub screw locking systems.

• Unbeatable Value for Money: The ideal alternative for replacing a lost fin or customizing your setup without breaking the bank.

The Breizh Rider Team's Advice

"The GX template is a shop favorite that we recommend all the time! If your longboard tail slides out too easily with smaller side fins, or if you want to convert your Single Fin to a 2+1 setup for extra grip in hollower Breton waves (like La Torche or Douarnenez Bay when the swell drops in), these 100 mm side bites work wonders. They lock in the rail, help you generate speed effortlessly coming out of bottom turns, and deliver real control under your back foot. A must-have to keep in your board bag!"
