Surf Fins Single Tab Rapid Side Fins (medium/black) - Eisbach Riders Surfing Company

Designed for River Waves

Tested on the Eisbach and in wave pools, our fins deliver the drive, control and quick response needed for fast, powerful standing waves. They’re built to protect your board — in hard impacts, it’s better to break a fin than damage the fin box.

And because their template and foil are designed for balanced all-round performance, they also translate seamlessly to ocean surfing — offering reliable speed, stability and smooth turns in small to medium beach breaks.

For extra looseness and agility on high-pressure waves, a small center fin can help unlock tight turns and playful maneuvers.
