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.
Friction leads to Power Loss
At the heart of a spinning reel lies the main shaft, a rod-like component visible when you remove the spool. This crucial part supports the spool and ensures the reel's smooth operation.
In traditional designs, the main shaft rubs against the pinion gear, causing friction. This friction dissipates the winding force, hindering efficient power transfer to the reel and leading to a loss of power.
A reel that can wind up easily even under heavy load.
The "INFINITYDRIVE" reduces friction by using a special low-friction bush to support the main shaft instead of a pinion gear. A special surface treatment on the main shaft further reduces power loss from friction. This allows the force used to turn the handle to be transmitted directly to the reel, enabling powerful reeling even under high load.
In the heat of battle with a massive fish, the angler will always dominate, maintaining control and never surrendering the advantage to the fish.

X-SHIP makes reeling easier
X-SHIP, much like INFINITYDRIVE, is a gear system designed to maximise the reel's winding efficiency
With the addition of X-SHIP, the drive gear's diameter was increased, the layout of the pinion and drive gears was optimised, and a structure supporting both ends of the pinion gear with two bearings was adopted. This results in a strong gear mesh and smooth reeling, even under heavy load.
Combining INFINITYDRIVE and X-SHIP creates a powerful synergy, making reeling smoother than ever. Anglers will especially appreciate this when battling large fish or using lures with high pulling resistance.

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.
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.
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.
