The Shimano 21 Ultegra reel marks a major upgrade, enhancing one of Shimano's most popular mid-range reels with cutting-edge technologies for an exceptional fishing experience.At its core, the 21 Ultegra combines Hagane Gear, MicroModule II, X-Ship, and Silent Drive, resulting in smooth, powerful winding even when battling tough fish. This synergy provides a seamless and efficient operation for anglers.For durability, Shimano's X-Protect technology ensures superior water resistance by shielding the line roller and roller clutch from water intrusion, extending the reel's lifespan and maintaining reliable performance in harsh conditions.When it comes to long-distance casting, the 21 Ultegra features a Long Stroke Spool design and AR-C Spool lip, enabling smoother line flow for greater casting distances. The lightweight CI4+ body reduces the reel's overall weight, making it comfortable to use during prolonged fishing sessions with less fatigue.
