Shimano SE4000FB Sedona FB Spinning Reel

Graphite Frame. Graphite Sideplate. Graphite Rotor. Cold Forged Aluminum Spool provides increased strength and durability. Spare Cold Forged Aluminum Spool (except model 750). S-Concept (only on model 750) 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 (only on model 750) lays the line in a parallel pattern for excellent castability and control. Maintenance Port (only on model 750) a sealed plug that can be removed using a screwdriver to easily lubricate the drivetrain without disassembling the reel. S-Arm Cam (only on model 750) a protruding surface on the bail arm keeps slack line in contact with the line roller to reduce the chance of tangles and line cuts. Fluidrive uses the successes of Fluidrive, but also uses a polishing process to increase tooth contact for increased efficiency. 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. 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. Ported Handle Shank (only on model 750, otherwise standard) reduces the overall weight of the reel. 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 quicker.
