TB50 | 50mm Hollow Titanium SW Power Knob | For Shimano Type-B | Gomexus

The titanium power knob (TB50 50mm Series) from Gomexus is the definitive high-sensitivity, ultralight round knob upgrade engineered for offshore popping, vertical jigging, and deep-sea gamefish battles. Precision-crafted from pure marine-grade titanium with an ultra-thin 0.6mm hollow wall structure and weighing an astonishingly light 0.88 oz (25.0g), this 50mm power knob delivers extreme bite conductivity, permanent saltwater corrosion immunity, and fatigue-free cranking leverage on Shimano Type-B platforms. Key Features & Performance Upgrades 0.6mm Ultra-Thin Hollow Titanium Shell: As an elite titanium power knob, the thin-walled unibody structure acts as an acoustic soundboard, instantly transmitting subtle bottom bumps, jig flutters, and tentative strikes directly to your palm. 0.88 oz (25.0g) Featherweight Advantage: Weighs nearly half as much as standard aluminum power knobs, dramatically lowering rotational swing inertia and preventing arm fatigue during aggressive jigging cadences. Low Thermal Conductivity All-Season Comfort: Natural titanium thermal properties keep the knob pleasantly warm in freezing sub-zero winter winds and comfortably cool under blazing summer sun. Gentle Pentagonal Non-Slip Finger Lock: Subtle 5-sided ergonomic contouring on the inner grip section cradles your fingertips, ensuring a locked-in power grip during sudden pelagic runs and wet conditions. Odor-Resistant & 100% Saltwater Proof: Highly polished titanium surface resists fish slime, salt crust, and grime—cleans effortlessly with a splash of fresh water without retaining fishy odors. Direct Fit for Shimano Type-B Shafts: Precision-machined for a direct drop-in fit onto Shimano 5000–20000 saltwater spinning and conventional reels without requiring drilling.
