Frequently Bought Together
The spool tension knob (Mechanical Brake Cap Series) from Gomexus is the premier cosmetic and functional upgrade engineered for Daiwa low-profile baitcasting reels. Precision CNC-machined from ultralight aircraft-grade aluminum and weighing an astonishingly light 0.06 oz (1.7g), this cap features aggressive diamond-cut knurling and a brilliant water-drop curved profile to deliver effortless one-finger spool play adjustments and long-lasting corrosion resistance.
Key Features & Performance Upgrades
- Diamond-Cut Non-Slip Knurling: As a performance-tuned spool tension knob, the 3D diamond perimeter texture ensures maximum friction against your thumb and index finger, making fine-tuning spool tension seamless during wet weather or cold-weather glove use.
- 0.06 oz (1.7g) Ultralight Aerospace Aluminum: Weighing next to nothing, this featherlight CNC-machined aluminum cap adds high-end custom styling without compromising reel balance or spool start-up dynamics on BFS setups.
- High-Gloss Mirror Anodized Coating: Features a specialized “water drop” curved top with high-gloss color anodizing that resists scratching, fading, and saltwater spray while adding an eye-catching accent to your reel.
- Instant Tool-Free Installation: Engineered with factory-tight thread tolerances, allowing you to hand-tighten the cap onto your reel frame in seconds without needing specialized wrenches.
- Direct Fit for Daiwa Flagship Platforms: Designed specifically for Daiwa Steez (1016 SV / 1012 SV / SV TW / CT / AIR), Zillion (SV TW / TW HD), Alphas (SV TW / AIR), Tatula TW 80, Morethan, and GekkaBijin AIR TW.

It didn’t fit but nice product
Wait a little longer, it’s beautiful on the cover.
It’s so beautiful, the color matches the stars.
After being decorated, it fits very well. It’s beautiful. Wait a long time, but it’s worth the price. If there is a new roller again, I will order from Gomexus.
The decoration must be this brand.
