NASCI offers high cost-performance specifications that meet the needs of a wide range of anglers. At the core of its smooth rotation and casting performance are Shimano’s signature technologies: HAGANE GEAR, X-SHIP, and AR-C SPOOL. COREPROTECT enhances water resistance without adding heavy rotational feel, ensuring durability in various fishing environments.

Building on this foundation, the new Nasci inherits advanced technologies from higher-end models, including INFINITYDRIVE, ONE-PIECE BAIL, and ANTI-TWIST FIN. These features deliver exceptional rotational sensitivity, toughness, and trouble-free performance at a high level, making it a reliable choice that strongly supports serious anglers aiming to step up their game.

At the heart of its smooth rotational performance lies the HAGANE GEAR, crafted from ultra-duralumin using Shimano’s proprietary cold-forging technology. Just like the previous model, it pursues an “unwavering reeling feel that lasts forever.”

The newly equipped INFINITYDRIVE significantly reduces sliding resistance between the pinion gear and main shaft, lowering rotational torque. This results in enhanced reeling power, allowing anglers to maintain control even under heavy loads with aggressive, offensive reeling.

What reinforces the powerful reeling performance of NASCI is its uncompromising body design and handle rigidity. The body is constructed from high-strength resin with excellent rigidity, protecting gear engagement with the optimal flexibility for PE line fishing.

Additionally, the handle is made of aluminum and shaped to suppress flex.
This design ensures that the angler’s input power is efficiently converted into reeling force without loss.

While being a versatile reel, NASCI also focuses on water resistance for reliable long-term use. Equipped with Shimano’s non-contact water resistance system, COREPROTECT, it prevents water intrusion through a water-repellent treatment that forms protective droplets. Because it’s non-contact, it minimizes deterioration of water resistance due to wear, maintaining the reel’s original smooth rotation.

Trouble-free performance is essential for an enjoyable fishing experience—especially line trouble, which can lead to reduced casting distance and weakened line strength. To prevent such issues, NASCI incorporates advanced technologies inherited from higher-end models.

ONE-PIECE BAIL smoothly guides the line without unnecessary movement, while the Anti-Twist Fin suppresses slack and prevents line drop-off, supporting clean and accurate winding. Additionally, AR-C SPOOL features a specially designed spool ring that streamlines line flow, suppresses backlash, and enables proper line release—fully maximizing casting performance to hit your target.

Focusing on smooth rotational performance and dependable durability, the Nasci continues to evolve without changing its core concept.

By incorporating advanced technologies inherited from higher-end models—such as INFINITYDRIVE, ONE-PIECE BAIL, and ANTI-TWIST FIN—NASCI has become an even more reliable reel for serious anglers. Despite these upgrades, the 2500 size is now 5 grams lighter than the previous model, making this evolution even more impressive.
