The Shimano Spheros SW Spinning Reels offer more to the angler with the new Shimano SW concept features.

X-Ship: X-Ship provides improved gear durability. By supporting the pinion gear on both ends with bearings, the pinion gear maintains precise alignment with the drive gear. This means the gears will stay in the same position under the heaviest loads. The added benefit is that friction between the spool shaft and gear is eliminated, enhancing the casting performance with lighter lures, and allowing for longer casts.
X-Shield: By providing dependable sealing structures and gaskets at necessary points throughout the reel, X-SHIELD is able to block water intrusion. This protection provides high reliability and durability when SPHEROS SW is used in extreme fishing conditions.
Shimano CF Gear: To deliver the toughness and performance level required by saltwater anglers, Shimano utilizes their cold forging technology to deliver a gear with incredible structural strength that provides the best protection against abrasion and damage.
