Experience the Innovation of Shimano's "SILENT TUNE" Technology
Shimano's groundbreaking "SILENT TUNE" technology enhances the performance of baitcasting reels by ensuring quick and smooth spool rotation. By applying precise pressure to the bearings that support the spool, "SILENT TUNE" significantly reduces vibrations during high-speed rotation, resulting in quieter casting and a seamless initiation of spool movement.
Mastering the Art of Quiet and Comfortable Casting
When casting a baitcasting reel, a higher spool rotation speed leads to increased vibrations, which in turn raises the likelihood of noise generation.
Shimano's innovative "SILENT TUNE" mechanism incorporates O-rings strategically located on both the inner and outer circumferences of the bearings. This design enhances the fit between the shaft and frame, effectively minimizing any rattling of the bearings.
As a result, the mechanism eliminates rotational loss in the spool, providing a remarkably quiet experience along with smooth, fluid rotation. It adeptly suppresses even the slightest vibrations, delivering an exhilarating casting sensation that elevates your overall fishing performance.

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.
The reverse tapered spool corrects the winding shape and reduces spool vibration.
Shimano’s "MGL SPOOL Ⅳ" features a reverse-tapered shape that is ultra-thin and designed for extremely low inertia.
It winds the line evenly and consistently. A well-spooled, balanced spool reduces spool vibration during casting, resulting in improved performance.
Versatile brake system: Adjust on-the-fly with an external dial for any situation.
The SVS centrifugal brake system offers precise casting capability thanks to its exceptional casting accuracy. This design allows anglers to hit their intended targets effortlessly, enjoying the benefits of lightweight reels that enhance performance with exciting line leaps and long-distance casts.
Introducing the lightweight revolution: The new concept magnet brake system.
The Finesse Tune Brake (FTB) system, which is adopted in Shimano’s bait reels, is a magnetic brake system that eliminates the brake unit from the spool, making it the lightest spool in Shimano’s bait finesse history.
