The aluminum reel power knob (A38 Series) from Gomexus is the ultimate ergonomic cranking upgrade engineered for saltwater spinning and baitcasting reels. Machined from one-piece aircraft-grade aluminum and available in 35mm, 38mm, and 41mm sizes, this spherical power knob delivers massive winching leverage, reduced hand fatigue, and silky-smooth rotation when battling hard-fighting striped bass, snook, and offshore gamefish.

Key Features
- One-Piece Solid Aluminum Build: As a heavy-duty aluminum reel power knob, the seamless CNC unibody eliminates flex and provides maximum structural rigidity under brutal drag pressure.
- Ergonomic Round Power Contour: Designed for an intuitive, full-palm grip that prevents slippage and finger strain caused by undersized factory plastic T-knobs.
- Rapid Drainage Porting: Precision-machined teardrop drainage slots allow saltwater, dirt, and fish slime to flush out instantly during post-trip rinses, ensuring long-lasting smooth bearing life.
- Dual-Color Saltwater Anodizing: Multi-stage anodized finish guards against harsh UV rays, saltwater corrosion, and scratch damage.

Lovely detail
Great options of spacer washers
I have these knobs on all my shimano reels .from my 8000 Saragossa to my stradic 3000’s .worth every penny
Fantastic! I love this upgrade! It fits so comfortably in the hand and the installation was so easy and quick. You got to get yourself one. I’m buying another for my father in law! Caught a hammerhead too!
Feels great to reel with. Much more comfortable when you have a larger or fighting fish. I bought some for my Diawa but have to return it for a handle due to rivets. Fits on Shimano great. Easy to install.
