Serious anglers, meet the Duo Spearhead Ryuki 51S - this little lure is an absolute monster for trout fishing! Measuring 2.0 inches (51mm) and weighing 5.5g, this sinking lure has been completely redesigned from the ground up. It's not just a simple weight upgrade - Duo totally reworked the body shape and internal structure to create something special. The Ayu color pattern (ANA4010) is incredibly realistic and triggers strikes even in tough conditions. What makes this lure so effective? It maintains the Ryuki bloodline's strong appeal and action while being versatile enough for both shallow and deep water presentations. The fixed center of gravity design gives it a stable, predictable action that fish just can't resist. Equipped with #10 hooks and #1.5 rings, this lure is built for performance and durability. The slightly increased weight from previous models makes it easier to handle with light tackle while allowing you to reach those deeper spots where big trout hide. Perfect for finesse presentations where subtle action makes all the difference. Whether you're targeting rainbow, brown, or brook trout, this lure's combination of size, weight, and action makes it incredibly effective. The quality construction means it holds up to multiple fish without losing its action or finish. If you've had success with previous Ryuki models, you'll be blown away by the improvements in this 51S version. It's that perfect balance of casting distance, sinking rate, and irresistible action that turns slow days into memorable fishing trips. Add this to your trout box - your catch rate will thank you!
