Eisbach Riders Flexible SUP River Fin (Quick Lock)

If you paddle rivers or shallow waterways, the Flexible SUP River Fin by Eisbach Riders is a smart upgrade for your paddle board setup. Designed specifically for shallow water paddling, this compact and flexible river SUP fin helps reduce the risk of damage when paddling over rocks, gravel, or low riverbeds.

At just 4.7 inches, this Quick-Lock paddle board fin keeps your board stable and responsive while reducing how deep the fin sits in the water. The flexible construction absorbs impacts from rocks and obstacles, making it ideal for adventurous paddlers exploring rivers, canals, and shallow coastal areas.

Whether you’re touring down a river, navigating shallow sections, or simply want a durable replacement fin, the Eisbach Riders Flexible SUP River Fin delivers reliable performance where traditional fins struggle.

Flexible Design for Shallow Water

Unlike rigid fins that can easily catch or break on rocks, this flexible river fin bends on impact, helping protect both your fin and your board. This makes it perfect for paddlers who regularly explore:

• Rivers and moving water
• Shallow lakes and canals
• Rocky or gravel-bottom waterways
• Coastal paddling with changing depths

Despite its compact size, the fin still provides solid tracking, stability, and control, allowing you to paddle confidently even in challenging environments.

Quick Lock Installation

This Quick-Lock / Smart Lock SUP fin installs in seconds without tools. Simply slide the fin into your board’s click fin box and lock it into place, no screws or tools required.
It’s also a perfect replacement paddle board fin if you’ve lost or damaged your original click fin.

Compatible Paddle Boards

This fin works with many inflatable paddle boards using Quick-Lock or Smart Lock fin systems, including boards from:

• Jobe (Pre 2026)
• Bluefin SUP
• Thurso Surf
• iRocker

Always check your fin box type to ensure compatibility with tool-free click fin systems.

We have been using these River Fins on our Jobe Paddle Boards for the last couple of years and in our opinion are among the best on the market. We can confirm compatibility with both Pre 2026 Jobe Premium inflatable paddleboards and Pre 20206 Jobe Elite inflatable paddleboards

Jobe have changed the fin box design on their 2026 paddleboards which are smaller so these fins will not fit but will fit Jobe paddleboards models with a Quick Lock system before 2026.

⚠️ Please note: This fin does not fit the Jobe Lite SUP series.
