Shimano's unique technological capabilities are the heart of the reel. The performance of these gears is determined by the precise design of the gear teeth, the advanced technology used to create them, and the gear structure that maximises their performance.
INFINITYXROSS distributes the load across a wider area of the gear tooth surface, resulting in exceptional durability.
Continuous Use will Cause Gear to Wear Out Over Time
As the reel is cranked, the gears are in a continuous state of movement. The drive gear, which rotates with the handle, and the pinion gear, responsible for moving the rotor, are truly the heart of the reel, enduring the majority of the load. Over time, as these gears experience extensive use, they may begin to wear down, leading to reduced smoothness in winding and impacting overall performance.
Minimising the load on the gear tooth surface significantly enhances durability.
Shimano has extensively researched technology to achieve smoothness while expanding the contact surface of the gear teeth. By evolving the design and manufacturing technology of the gear tooth surface, Shimano has successfully increased the contact area between the drive gear and pinion gear.
This innovative design ensures that the load on the gear tooth surface is distributed across a larger area, effectively preventing localized damage and greatly enhancing durability compared to traditional models. Even the most dedicated anglers can relish in smooth and powerful reeling for extended periods, ensuring a consistently enjoyable fishing experience.

Our goal, effortless reeling.
Shimano's reel design concept aims for “eternally smooth reeling.” The result is HAGANE. Shimano honed its proprietary metal processing technologies with precision cold-forging technology and refined them over many years to develop reels that only Shimano could deliver.
Reduced line release resistance for an optimised casting experience.
The line is meticulously wound around the spool, ensuring a tight and organized configuration that greatly minimizes line release resistance. This refinement enhances the casting experience, enables smooth line retrieval, and heightens sensitivity during the fall, allowing for more precise control and responsiveness.
Seize control with powerful reeling.
When the rod bends powerfully and you grip the handle knob to stop the target's escape, the reel's design ensures smooth power transfer, giving you the upper hand in the fight.
Shimano's INFINITYDRIVE eliminates those frustrating moments, ensuring powerful reeling even under high load. With this technology, you'll be able to land big fish that once seemed impossible to catch.
Anti-twist fin: A fin that suppresses line slack.
Every angler has faced line trouble at some point. Shimano's "ANTI-TWIST FIN" tackles this issue by suppressing line slack, reducing the chances of the line dropping out of the lower part of the spool or wrapping around the spool while twisted.
