IOS FACTORY S-System Power for Shimano

Linear response, the minimum required, even for fighting big fish!

Strong hooking bower

High-precision drag unit provides a high-pitched mechanical drag sound.

IOS SSystem Power is the one and only Drag System.

S System Power is a drag system for mid-size Shimano reel models.

Loosening the drag gives the fish the initiative. When the drag is tightened, it is instantly run and cut. We want the thick shaft hook to penetrate the hook, even when casting long distances. This is the ultimate drag system that combines the contradictory characteristics of conventional drag systems, such as the need to properly follow the gills and jumps of fish, and the need to provide constant tension to prevent fish from being caught.

The lightweight, high-strength, high-precision machine-cut one-piece housing made of ultra-super duralumin, the spool holder, called the second drag washer, and washers are made of a newly developed impregnated oil resin with excellent wear resistance characteristics.
It combines high-precision drag characteristics with strong hooking power and drag response that transitions linearly from the initial movement.

It is also suitable for rockfish fishing around cover where power game near reel breaking strength is required, shore jigging around rocky shores, and offshore ferocious game fish such as dolphinfish and bluefish, etc., with a high and comfortable drag sound that rivals are jealous of, similar to the Ferrari V12 sound in the early 90s, and it shows the best drag performance.

* The S system takes the drag characteristics of the reel to the limit and to the extreme, which may put unimaginable strain on the rod and body, not to mention the line and hook.

* When the 14 STELLA is attached, even if the drag is tightened, there may be a case that tension is not applied.
If this is the case, please add one additional piece of the supplied felt to accommodate.

* Not compatible with lever brake specifications.

* SW series and those with drag ratchets built into the spool cannot be fitted.

* However, the STRADIC Ci4 4000 series is applicable to the conventional S-system.
