S-Concept represents Shimanos initial philosophy on which many of our spinning reels have been designed. The three basic ideas that are inherent in the S-Concept are Smooth, Silent and Strong.

Slow Oscillation lays the line in a parallel pattern for excellent castability and control.

S-Arm Cam protruding surface on the bail arm keeps slack line in contact with the line roller to reduce the chance of tangles and line cuts.

Maintenance Port a sealed plug that can be removed using a screwdriver to easily lubricate the drivetrain without disassembling the reel.

A-RB (Anti-Rust Bearings) are specially treated stainless steel ball bearings that are at least 10 times more corrosion resistant than standard stainless steel ball bearings.

Fluidrive II uses the successes of Fluidrive, but also uses a polishing process to increase tooth contact for increased efficiency.

Super Stopper II is a one-way roller bearing that eliminates backplay for solid hooksets, yet can be turned on or off to allow back-reeling.

Dyna-Balance similar to balancing a tire, we use counterbalancing techniques in the rotor to eliminate wobble during the retrieve.

Power Roller II is an oversized line roller that reduces twist from casting and retrieving and is enhanced with a tapered area on the support to help line get onto the roller.

Floating Shaft By using a bearing or bushing, friction is reduced between the pinion gear and spool shaft for increased smoothness and durability.

Metal Series (except model 750) Metal frames keep moving parts in precise alignment for increased efficiency and durability.

Ported Handle Shank (only on model 750) reduces the overall weight of the reel.
