SURF SYSTEM THRUSTER SET FCS1 G5 | SET OF 3 FCS-COMPATIBLE SURF FINS

The fins your board needs: the Surf System Thruster Set FCS1 G5, performance and compatibility without complications

If you are looking for reliable thruster fins that are easy to install and offer unbeatable value for money, the Surf System Thruster Set FCS1 G5 is exactly what you need. Three composite fins in size M, designed following the G5 template—the most popular in the world for stock surfboards—and compatible with the FCS1 dual-tab fin box system. No complications, no surprises: they fit, they hold, and they perform.

WHY THESE FINS MAKE THE DIFFERENCE

The G5 template is the universal benchmark for the modern thruster: a balanced shape that combines drive, hold, and maneuverability in all types of conditions. Surf System takes this proven geometry and offers it in a high-rigidity composite material, ideal both for surfers looking for replacement fins and for those who want to have an extra set in their travel bag without worrying about dings or wear.

• Universal FCS1 compatibility — they fit any board with dual-tab FCS fin boxes; also compatible with FCS2 using screws (not included)
• G5 template — the most widespread thruster shape on the market: wide base for drive, medium height for control during maneuvers
• Composite material — good rigidity for transferring energy to the board, with a touch of flex at the tip that facilitates surfing for beginner and intermediate levels
• Size M — designed for surfers between 60 and 90 kg, suitable for shortboards, funboards, and mini-mals
• Complete set of 3 fins — ready to install, no need to buy additional parts
• Excellent value for money — the smartest choice as a spare set or for a second board

ADVICE FROM OUR EXPERTS

The G5 fins are the ideal starting point if you are learning to perceive how fins affect your board's behavior. Test them in varied conditions—small, punchy waves, onshore wind, clean groundswell days—and you will see that the G5 template performs well in almost all of them. When you notice that you want more pivot or more drive, you will have learned exactly what to look for in your next set. If your board uses FCS1 boxes, remember to always carry spare screws with you: they are the most commonly lost items during a rushed fin change before hitting the water.

SURF SYSTEM GUARANTEE — FINS FOR ALL LEVELS

Surf System is a brand specialized in entry and mid-range surf accessories, distributed throughout Europe via large specialized retailers and independent surf shops. Their philosophy is simple: offer technically sound products at a price that doesn't exclude anyone from the water. The Thruster Set FCS1 G5 is the most representative product of that philosophy: a fin with the correct shape, the right material, and the compatibility that most boards on the market need. No unnecessary extras, no inflated price.

All Surf System fins are manufactured under quality control and tested to ensure that the fit in FCS1 fin boxes is precise and secure. The official warranty covers manufacturing defects from the time of purchase.

USAGE AND CARE

• Installation: insert each fin into its FCS1 box by aligning the two tabs with the box holes. Tighten the set screws (not included; an FCS-compatible hex key is recommended) firmly, without forcing.
• FCS2 compatibility: these fins can be installed in FCS2 boxes using specific adapter screws (not included and sold separately).
• Check: check the tightness of the screws before each session, especially during the first few uses.
• Cleaning: rinse the fins with fresh water after each session in the ocean to prevent salt buildup on the tabs.
• Storage: keep them in a dry place, away from prolonged direct sunlight to preserve the composite material.
• Caution: avoid direct impacts to the tips of the fins and do not overtighten the screws to avoid damaging the box.
