The "INFINITYLOOP" system offers an ultra-super slow oscillation that surpasses the Super Slow Oscillation System
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.
The Beginning of the Super Slow Oscillation System
The Super Slow Oscillation System was first introduced in the limited-production "STELLA Millennium Edition" model in 2000, and later adopted in the STELLA 1st and 4th models
Oscillation refers to the forward and backward movement of the spool. Super slow oscillation technology allows the spool to move up and down slowly as the reel is wound, ensuring the line is wound tightly on the spool.
This technology ensures the line is wound extremely tightly. The Super Slow Oscillation System significantly enhances casting distance and feel, making it a popular topic among anglers due to its outstanding performance.
An Exhilarating Casting Feel and Improved Casting Distance
In 2022, the advanced Super Slow Oscillation System was incorporated into the "22STELLA". The spool's up-and-down movement speed has been significantly slowed down through internal structural enhancements. This innovation, known as "INFINITYLOOP", represents an "ultra-super slow oscillation" technology that surpasses the previous super slow oscillation system.
With the ultra-super slow oscillation technology, the line is wound onto the spool evenly and each turn is parallel, lying close to the next.
This advanced design dramatically reduces line release resistance, offering an exceptionally smooth casting experience. Anglers will feel as if they're releasing an arrow, almost forgetting the line is there. It enhances casting distance with minimal effort and improves fall speed stability and sensitivity after the lure hits the water.

Smooth Drag Performance
The advantages of "INFINITYLOOP" extend beyond enhanced casting performance.
When the drag is activated, the line's angle from the spool to the line roller changes less frequently compared to conventional products, ensuring smoother drag control. This reduction in frictional resistance between line turns means that even during sudden pulls from a fish, the line is released effortlessly and smoothly
Immerse yourself in the thrill of INFINITYLOOP
Spinning reels equipped with "INFINITYLOOP" technology also feature "PROPULSION" and "ANTI-TWIST FIN" to tackle line issues head-on. These cutting-edge innovations deliver an unparalleled casting experience, bringing a new level of excitement to anglers.

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.
Experience an exceptional gear system designed for high performance and unwavering durability.
INFINITYXROSS distributes the load across a wider area of the gear tooth surface, resulting in exceptional durability.
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.
