Firewire The Groove 5 Fin Set (Medium/Large)

Machado Groove Fin Set – High-Performance Surfboard Fins

A throwback to Rob Machado's high-performance surfing days, the Machado Groove Fin Set is his most advanced performance fin template to date. Designed for maximum speed, drive, and response, this fin set reflects Rob’s ongoing exploration of high-performance surfing.

Rob meticulously crafted these fins with progressive flex technology, ensuring the leading edge remains stiff for instant response, while the trailing edge flexes for enhanced spring and liveliness. The combination of carbon layups and a bamboo core creates the perfect balance of control, power, and flow through every turn.

This 5-fin set was designed specifically for the Groove surfboard model, but it can be used on other boards as well. While Rob originally shaped the Groove as a thruster, he quickly fell in love with the quad setup—leading to this versatile 5-fin design.

Available in Medium/Large, these fins offer a unique size profile—larger than a standard Medium but smaller than a typical Large, making them ideal for surfers seeking maximum performance and control.
