HAGANE is a Shimano reel design concept created to withstand continual use and extreme abuse. HAGANE is an innovation with built-in toughness and durability that works alongside Shimano's precision engineering. HAGANE is for all anglers.

With amazing strength and durability, the HAGANE Gear is at the very heart of most Shimano reels. Shimano, through the application of state-of-the-art technologies, gives anglers the long-lasting smoothness and enjoyment 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 result of Shimano's endless pursuit for durability — this strength and power of forged metal continue to represent the fundamental concept of Shimano reels.

X SHIP provides improved gear performance. Large diameter drive gear, optimally positioned pinion gear and drive gear, and two points bearings supported pinion gear produce light reeling under load.

INFINITYDRIVE is a new main shaft supporting structure that improves winding torque and allows for incredibly smooth and light rotation.

The basic design of the entire body and drive-related parts were reviewed one by one to reduce minute rattles, gaps, and shaking between parts down to the smallest detail. It provides smooth and quiet reel rotation.

Elastic fins are installed in close proximity to the line roller section. By suppressing line slack, the fins reduce the phenomenon of line dropping out of the lower part of the spool and line wrapping around the spool while the line is still twisted.

The water-repellent treatment provides water-resistance even in the presence of minute gaps due to the water bead formation effect. The water resist effect can be improved without increasing rotational resistance. Furthermore, since there is no contact, there is no abrasion and the waterproofing effect lasts longer.

G FREE BODY technology has been developed to shift the reel's center of gravity closer to the rod. By moving the center of gravity closer to the angler’s hand, the G FREE BODY helps to reduce fatigue and enhance casting comfort.

The spool has a special spool ring shape. This creates a rectifying effect on the line and realizes both suppression of line trouble and long casting performance.

The CROSS CARBON DRAG provides the smooth drag release and the durability.

ONE-PIECE BAILallows 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.
