Concentrated fish-catching power for serious anglers. This top-of-the-line reel is full-to-bursting with fishing prowess; Shimano integrated virtually every high-end feature at its disposal in this lightweight, low-profile reel. It boasts a team of six specially treated A-RB® bearings for consistent smoothness on casting and retrieves. An additional A-RB Super Stopper™ roller clutch bearing eliminates backplay for instant hooksetting power. High-efficiency HEG™ gearing permits no flex in the gear box to eliminate gear binding and raise the leverage threshold for superior torque on aggressive retrieves. The VBS™ centrifugal braking system prevents backlashes and maximizes casting distance by dynamically adjusting pressure on the spool during each cast. The Super Free™ pinion system eliminates friction on the spool shaft during casting for greater freespool. Ultralightweight A7075 aluminum spool with ported Magnumlite™ engineering provides peak strength with less weight. Its Dartainium drag can tolerate extreme heat stress. Reduced-mass VBS hub. Cold-forged aluminum frame, sideplate, drag star and handle shank. High-traction Septon®-coated grips
