Rainbow Fin Company SpeedWings Thruster

The winglet design at the tip of the fin reduces vortex drag, which is the turbulence created as water flows off the fin. By minimizing this resistance, the fin converts that energy into forward thrust, helping you maintain speed through turns and accelerate more easily.

Yes, these are designed for versatility. You can use them as the front fins in either a thruster or a quad setup, allowing you to keep your existing rear fins while upgrading the speed and efficiency of your board.

These fins are specifically optimized for shortboards. With a depth of 4.65 inches and a base of 4.25 inches, they are sized to provide the responsiveness and drive expected from a performance shortboard setup.

Because they focus on reducing drag and increasing acceleration, most riders describe the feeling as 'looser' in terms of glide and speed, but with more control. You will likely feel like you have an extra gear when pumping down the line.

Not necessarily. Since the SpeedWings are compatible with existing quad or tri-fin setups, you can simply swap out your front fins to experience the performance benefits without needing to overhaul your entire board configuration.
