Shimano made some key upgrades as well to improve the reel’s overall performance. The new Magnumlite rotor for one, features an asymmetrical shape that greatly improves rotation start-up, making it easier to start your retrieve. The Magnumlite rotor also greatly reduces inertia at the end of the retrieve for overall smoother winding and functioning. Shimano’s Coreprotect technology provides increased corrosion protection and water resistance for longer lasting performance, and advanced Hagane Gearing offers impressive power on the retrieve and the smooth precision anglers have come to expect from the Stradic CI4+. Stronger, lighter and smoother than ever, the Shimano Stradic CI4+ Spinning Reel isn’t pulling any punches.
