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. (Aero
Wrap II is not available on Saros reels, which are equipped
with Slow Oscillation.)
This feature eliminates wobble during the retrieve by counter
balancing the rotor to enhance sensitivity and smoothness. By
using computer balancing, an approach similar to car tire
balancing, we are able to redistribute the rotor weight to
create smooth rotation and eliminate vibrations caused by the
Fluidrive II

Building upon the successes of Fluidrive, which provides
extremely tight tolerances and control in the cutting process,
Fluidrive II polishes the gear surface to maximize tooth
contact. This increases the efficiency of the retrieve for more
power with less effort.
Super Stopper II anti-reverse uses a one-way bearing that
eliminates backplay.This provides the angler with instant
hooksetting power. In some reels, the Super Stopper II can
be turned off to allow backreeling for special techniques and
The SR-Concept combines the new concept of Reliance
with all aspects of the S-Concept: Smooth, Silent and
Strong. The Reliance Concept, or R-Concept, means that
dreams in reel design are now evolving into reality. The
result of the use of the new S-R Concept in design is the
development of many exciting new features.
S-Concept represents Shimano's initial philosophy on
which many of our spinning reel have been designed. The
three basic ideas that are inherent in the S-Concept are
Smooth, Silent and Strong.
•Smooth rotation and comfortable retrieve, coupled with
excellent drag performance and longer casting distance,
leads to our smooth, flawless operation.
•Silent operation of parts within the reel's construction
represents the attention to tight tolerances, reducing
excessive noise and resulting in the silent operation of our
•Strong, solid and functional construction leads to powerful
torque and durable drivetrains. This gives anglers the
strength and confidence they need to battle elusive
•The new sizing of our S-Concept reels offers anglers a
bigger spool and smaller body, resulting in a lighter, more
comfortable fishing experience without sacrificing line
The end result are reels offering anglers smooth, silent
and strong reels that are designed for years of fishing use.
The knowledge of fishing and the minds of Shimano's
engineers have given today's angler state-of-the-art reels
that are ready for any challenge.
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. This means longer casts
with less friction. The Propulsion spool also utilizes a long
stroke design to further enhance the casting distance.
Furthermore, there is less bouncing of the line on the spool
lip like on a standard spinning spool. Because of the
unique shape of the Propulsion spool, the line flows
consistently off of the spool. So, with a standard spool,
friction alternates from heavy to light as the line slaps the
spool lip. This causes backlash and inconsistent line
speeds. The Propulsion spool lip provides consistently
light friction to overcome these situations.
Paladin Gear Durability
Enhancement Spinning Using a
special cold forged aluminum drive
gear and a hardened brass pinion
gear (Stainless Steel pinion gear on
Stella SW), reels equipped with the
Paladin Gear Durability
Enhancement will retain their
out-of-the-box smoothness much
longer than before. In fact, testing
has shown that this combination of
metals is more durable than an
all-stainless steel drivetrain while
maintaining the smoothness that
Shimano is famous for.
