SHIMANO Thunnus CI4 Spinning Reel

Seemingly against the laws of nature, lightweight with the power to stop big fish are not words commonly found together in a sentence. Thunnus CI4 takes a page from Shimano’s bicycle division and uses carbon materials in high-impact situations in response to anglers wanting a reel with bait-running functionality but in a lightweight body. Thunnus CI4 is up to 7 ounces lighter than its predecessor without sacrificing any power and incorporates new drag systems for the main drag as well as the baitrunner drag. Thunnus CI4 is the most efficient live bait spinning reel on the market with unmatched adjustability for fishing live bait in any condition while still having the smooth stopping power.

Features: 

• HAGANE Gear: With amazing strength and durability, the HAGANE Gear is at the heart of most Shimano reels. Shimano, through the application of state-of-the-art technologies, gives anglers the long-lasting smoothness and pleasure that is felt when anglers first use a reel, over and over again. No cutting work is applied to the teeth of the drive gear during fabrication, instead the entire surface is calculated in minute detail by a special 3D-design and then formed by Shimano’s cold-forging technology. The result is assured resilience. HAGANE Gear is the fruit of Shimano’s inexhaustible pursuit for durability- the strength and power of forged metal continues to represent the fundamental concept of Shimano reels.
• Propulsion: The spool has a special ring shape. This creates a rectifying effect on the line and realizes both suppression of line trouble and long casting performance.
• C14+ Spinning:  C14 is a Shimano original material reinforced with carbon fiber that is lighter and has a higher strength than conventional resin material. C14+ is an advanced version of the original C14 material and is 2.5x more rigid than its predecessor. While improving lightness and rigidity, reel bodies and rotors built with C14+ are further reduced in size and weight.
• S A-RB Spinning: S A-RB bearings are put through the same process as Shimano’s A-RB bearings but feature shields on both sides of the bearings. These shields reduce the possibility of salt or sand inhibiting rotation of the bearing.
• One-Piece Bail: One-Piece Bail allows the line to travel unimpeded to the line roller. The seamless design reduces friction and decreases the chance of tangles or the line catching on the bail arm.
