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.

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.

The ultra-compact precision gear and the elaborate body housing realize a "silky" winding feel that has never been experienced before. SHIMANO's unique gear system that reduces the vibration level to less than half in a vibration comparison with conventional gears (our comparison), and achieves a smooth feeling without sacrificing strength by increasing the number of gear teeth that mesh with each other.

The HAGANE Body is a metal reel body with high rigidity. The body rigidity and impact resistance virtually eliminates body flexing on the reel while fighting fish. The result transforms the angler's actions directly into cranking power, increasing efficiency through strength.

Infinity Drive technology is an advanced structure that produces more powerful and exceptionally light winding within conventional and low-profile reels. This innovative design supports the pinion gear with the spool shaft rather than supporting the pinion gear with a bearing on the spool side. Infinity Drive within low-profile and conventional reels also optimizes the support distance and pinion gear thickness to achieve high support rigidity so that anglers can actively wind under heavy loads without compromising gear strength.

X PROTECT provides high-level water resistance to the inside bearing of drive gear shaft with waterproof construction.

S-Compact Body allows for all-day comfort and improved fishability by making the palming side plate up to 25% smaller than the A-Side plate.

The Cross Carbon Drag material provides a wider range of drag settings compared to traditional drag materials. The Cross Carbon Drag provides the smoothest Shimano drag performance ever while providing anglers with increased durability.

Exciting Drag Sound technology enables drag sound on a baitcasting reel without using the function of a rattle or clicker. This ultimately makes it easy for an angler to determine whether a fish is pulling drag and provides an advantage during the fight.
