Shimano Stradic ci4 Spinning Fishing Reel Review

The CI4 4000 is one of the upgraded version among the four main CI4 versions. With its striking good looks, lightweight with a solid feel, and an ultra-smooth reeling experience it has combined all features that win the hearts of many anglers all over the world.

All these exciting new features on the new Shimano Stradic CI4+ are designed to make to last.

By looking at these details, we can already tell that all these model designs are for light-weight baits like jerk baits and jigs. The reel’s lightweight construction facilitates its spinning through a large area of water intensely for an extended period without getting fatigued. In other words, Stradic CI4 specialization is for finesse type applications. The fact that CI4 specialty matches the finesse type of use is the reason why it was the most prevalent choice among 42 pro anglers for bass fishing.

​Grades Compared to Original Version:

Several updates were made to the original version of the CI4 reel making it a premium upgrade. The following are the main features, which separate CI4 Plus from its original version;

CI4 4000 construction:

Ci4 construction frame material is a characteristic only found in Shimano products. In more scientific terms CI stands for carbon interfusion, and 4 is the number of electrons inside that carbon atom. Straightforwardly, the frame material is just a reinforced carbon material. The carbon interfused element has a unique benefit in that it maintains the durability, and at the same time it weighs up to 25% less than other same sized reels.

Of great importance is the fact is that CI4 does not contain any metal, and they can remain untouched by rust, and no corrosion takes place. Shimano Stradic CI4+ is, therefore, a noble choice for saline waters.

X-Ship gearing:

Advance in technology has led to the development of X-Ship technology that supports the pinion gear on both ends with special bearings. The purpose of the system is to ensure that all reel-gears will stay in alignment even under weighty loads. This X-Ship technology has dramatically improved the rotating performance that in turn makes rotating much smoother. Fun fact is that this technology decreases the wear and tear on drag over time resulting in an extended lifetime of the gear system.

Paladin Gear Durability:

More fascinating is the fact that Stradic CI4+ uses unique cold forged aluminum on the drive gear and hardened brass on the pinion gear. While these materials are combined, it has been proven to last longer than the commonly used stainless steel. Advantageously, the combo helps retain the smoothness that Shimano is known for, and makes it stay for a more extended period.


  • ​It is lightweight
  • ​Enjoy smooth fishing on another level
  • ​It is nearly waterproof
  • Shimano Stradic Ci4 400 has rapid fire drag


  • ​A disappointment while using CI4 4000 is that you cannot comfortably enjoy fishing offshore.

  • ​CI4 4000 cannot withstand big catches like big sharks and bluefish. If you are looking to head out far off the shore, then this is not the reel for you! However, if your goal line is to catch bass, then this is the perfect spinning reel for that purpose!

How Shimano Stradic C4I 4000 Matches Other Similar Reels?

Almost all reels have practically the similar features and carry several main principles that are popular amongst them all. To begin with, weight, the CI4 + is lightweight, and it is in the weight range of 6-9oz which is common to other models. The high gear ratio is also a frequent resemblance among several reels. The gear ratio ranges from 6.0:1 to 5.8:1 and this is pretty much the same gear ratio. Max drag logically increases with each version, starting from low 7lbs and ends up not high too, that is 20 lbs. So it is best to limit yourself to freshwater fishing. All versions of the CI4 brand have six bearings.

Our Thoughts:

Shimano Stradic CI4 4000 review describes this great reel to details that it does not need additional words!

That said, and the addition of exclusive gearing updates and new CI4+ frame, CI4+ is even more desirable!

It has all the features that skilled angler needs and the fact that it comes with extremely lightweight can keep you continually casting for hours! A frame that preserves strength despite the weight and smoothness of drag is all an angler can ask!
