If you place the mechanism switch in the anti-reverse position, you will notice zero movement of the handle due to the Super Stopper II. Flawless at all times in its practical functions, it includes micro-adjustments for quiver tips or for use with bite alarms.

The excellent distribution of the line on the spool is the most essential feature for long and accurate casting. Shimano's revolutionary 'Varispeed' system consists of two gears. One is oval and the other is square. Only the highly specialized program created by Shimano can make the two gears work harmoniously. The result is the perfect parallel winding of the line.

The key point in the mechanisms is where the shaft comes into contact with the spool. The designers of the mechanisms minimized the gap at the contact point by placing bearings on both sides of the shaft. The result is that the mechanism operates smoothly under any conditions.

The SR arm consists of a single piece and does not allow the line to slack during use. The stainless steel dramatically reduces twists by directing the line to the line roller at greater speed.

Increases smoothness and balance while simultaneously being able to handle the loads transferred by the internal parts of the mechanism.
