Shimano SW Spheros HG Reel

More than just a support bearing, X-Ship is a combination of a cold forged main gear married with a brass drive gear. The two metals don't eat away at each other, providing longer lasting performance, as well as a smoother, more powerful retrieve. Shimano's X-Ship takes spinning reel technology to a whole new level. Anglers will experience increased gearing efficiency and power, providing for ultra-ligh handle rotation. By using a large diameter drive gear, moving the pinion gear closer to the center of the drive gear to provide 20% more power, and by supporting the pinion gear with two ball bearings, X-Ship provides a smooth, effortless retrieve, and also virtually eliminates the pinion gear twist and rotor flex common with most spinning reels when fighting a fish. X-Ship provides anglers with smoothness right-out-of-the-box.

Propulsion Line Management System: Propulsion Spool Lip, SR One-Piece Bail Wire, Power Roller III, Redesigned Bail Trip, S-Arm Cam - The most obvious component of the Propulsion Line Management System is the new Propulsion spool lip design. Through tens of thousands of casting tests and computer simulations, it has been determined that this new spool lip design provides longer casting distances than a standard spool lip design, while preventing backlashes and wind knots from forming. It also allows the line to flow off of the spool in smaller loops during the cast, which means less slap on the stripper guide. The Propulsion spool also utilizes a long stroke design to further enhance the casting distance.

Aero Wrap II is a worm gear oscillation system with a specially designed pitch to create optimal oscillation speeds for the Propulsion Spool Lip design. It provides uniform line lay and winding shape to prevent loss of energy during the cast, while providing longer casts than other oscillation systems. So, casting distance increases with less effort required.

These bearings have been through the same process as Shimano's A-RB bearings, but feature shields on both sides of the bearings that reduce the possibility of salt or sand inhibiting the bearing's rotation.

The Hagane Body is a metal reel body with high rigidity. The body stiffness and impact resistance virtually eliminates body flexing. The result transforms the angler's actions directly into cranking power.

Cross Carbon Drag. This drag material provides a wider range of drag settings, along with the smoothest Shimano drag performance ever.

The Hagane Drive Gear is produced by Shimano's coldforging technology, without the need for additional machining. This delivers a longlasting smoothness, strength, lightness and power at the very heart of the reel. Traditional diecast, machined gears are less durable under heavy loads.

CoreProtect is Shimano's water resistance technology, a special coating designed to provide water resistance without that heavy rotation feeling.
