Re-engineered for 2020, the Shimano Metanium MGL B Baitcasting Reels utilize never before seen technologies to achieve the pinnacle in baitcasting reel performance. The newest iteration of the renowned Metanium line of reels boasts a cutting edge body design that easily cements it as the most advanced Metanium to date. Featuring a revolutionary single-piece Magnesium Core Solid Body, the Metanium MGL B takes strength and rigidity to heights previously unreached by low-profile reels. The Core Solid Body design enhances sensitivity by more efficiently facilitating the transmission of vibrations to the angler's hands, giving them more opportunity to pick up on even the most subtle tick and bump of their lure, even on slack line. The magnesium frame material is extremely lightweight and offers superior corrosion resistance in freshwater environments. Housed within the single-piece frame is an all-new Micro Module main gear system cut from solid brass, which is a significant upgrade over the previous generation?s aluminum gear. Crafted from a much harder and stronger metal, these new gears provide longer lasting, reliable performance with the unparalleled smoothness anglers have come to expect from Shimano's fine toothed Micro Module Gear. For the ultimate experience in precision, long distance casting, the Metanium MGL B is fitted with an MGL III Spool. These ultra-lightweight, high velocity spools reduce spool inertia by 17% compared to the previous generation, allowing for superior casting distance with lighter lures that are notoriously more difficult to cast. Difficult casting scenarios such as skipping jigs under docks or casting light baits into the wind will become easier with the MGL III spool, as the lower spool inertia allows the SVS Infinity braking system a wider range of adjustability for maximum control with all ranges of lures. With a full line-up of proprietary Shimano technologies, the Shimano Metanium MGL B represents the pinnacle in baitcasting reel perfo.
