Kattobi Tuning Kit ZHi
Type: ZHi (HRCB Corrosion-Resistant Bearing + Double-Shielded BB)

Type: ZHi (HRCB Corrosion-Resistant + Double-Shielded BB) is a saltwater-ready, all-round BB that boasts more than 10 times the corrosion resistance of conventional models thanks to HRCB.
In combination with double shields that excel at corrosion protection, it delivers outstanding durability.
It is a versatile bearing that lets you cast with confidence in any field—not only for black bass, but also from rockfish to offshore targets.

Replace the spool bearings in your baitcasting reel for Kattobi tuning!
Improved initial spool start-up at the moment of casting greatly increases lure flight distance!
Compatible with Japanese baitcasting reels such as SHIMANO, DAIWA, and ABU, as well as reels from American makers!
HEDGEHOG STUDIO’s Kattobi Bearings are adopted by pro shops and manufacturers nationwide.


Why Do HEDGEHOG STUDIO Kattobi Bearings Cast So Far?

From selecting raw materials to machining, assembly, and inspection, production is carried out under strict domestic quality control.
Each finished bearing is carefully inspected by artisans, and only those that pass are treated with our original oil and shipped.
Because they are genuine MADE IN JAPAN bearings, this level of quality is possible.



* When casting lures over 20g to full distance, all bearing types achieve nearly identical maximum distance. However, for pitching and short-range control, AIR Bearings are superior.
(For lures under 20g, AIR Bearings significantly outperform standard bearings in both distance and controllability, especially for finesse casting.)

AIR BFS Bearings offer higher startup performance than AIR Ceramic Bearings. However, AIR BFS is not necessarily more effective in all situations. BFS Bearings are especially strong in lure weights under 10g. For a balanced all-round choice, AIR Ceramic is recommended.
For lure weights above 20g, AIR HD Ceramic is optimal.

* When using in saltwater, always select AIR Ceramic Series bearings. BFS is not suitable for saltwater use.
* For heavy lures (over 20g), maximum distance performance is achieved with AIR HD Ceramic Bearings.

The chart above is based on the assumption of casting with lure weights.
Note that actual performance varies depending on reel type, rod, and casting style.
If you frequently use lures over 20g, or saltwater applications such as shore casting and offshore jigging, ZHi Bearings are also recommended.

If corrosion resistance is your top priority, select AIR HD Ceramic Bearings. Otherwise, ZHi Bearings are recommended.
