Shimano Stradic FK Spinning Reels are constructed with a Hagane body to provide stiffness and impact resistance to virtually eliminate body flexing. The Hagane gear gives you long-lasting smoothness, while the cold-forged spool provided strength and durability. These reels offer improved balance and weight to help reduce fatigue. Stradic FK reels are equipped with Shimano's Propulsion Line Management System with Aero Wrap II Oscillation, setting the standard for design and durability. Stradic FK Spinning Reels feature Shielded A-RB Bearings and Fluidrive II technology for extremely smooth operation. The Power Roller greatly reduces line twist to minimize unwanted loops and prevent line tangles. Every part of each Stradic reel has been designed to offer anglers the best in performance and power.
