Shimano's newest innovation in brake system technology, SVS Infinity, provides easy-to-manage, consistent spool control and brake force. With brake weights that use inner friction against the raceway during the cast, SVS Infinity controls spool speed for precision casting, especially when using lighter lures. The external adjustment knob provides for quick, precise adjustments when anglers need to adjust to the conditions or when they switch baits.

Super Free Spool eliminates friction on the spool shaft during the cast. Standard baitcasting reels are constructed in a way that when the clutch bar is pressed down, the pinion gear is freed and can actually drag on the spool shaft. This creates friction that can limit the length of a cast. But baitcasting reels with Super Free Spool are constructed so that the pinion gear is supported by a ball bearing. When the clutch is disengaged in preparation for a cast, the pinion gear and spool shaft are kept in perfect alignment. The result: zero friction is placed upon the spool shaft and enhances casting performance.
