The Facts: The Shimano Symetre spinning reel features 4 A-RB anti-rust ball bearings and a Super Stopper II anti-reverse roller bearing; a Fluidrive II polished oversized drive gear; Dyna-Balance rotor to eliminate wobble during the retrieves; and the slow oscillation creates perfect line lay for superior casting distance and maximum contact with your bait or lure during the retrieve. The solid, non-flexing frame (graphite on the 750) and graphite rotor and sideplate provide superior durability without adding weight. The Power Roller II (III on the 750 model) reduces line twist. The FB reels have a Floating Shaft to reduce friction between the pinion gear and spool shaft for smoothness and durability. RI series feature a rear Fightin' Drag.
