Product Description

You can add one bearing to the worm shaft of the 24 Metanium DC, 23 Metanium, 22 Metanium Shallow Edition, and 20 Metanium.
Upgrading the worm shaft to a 1BB specification reduces rotational resistance, making the reeling feel lighter and smoother.

This product is a tuning kit, Not a fishing reel.
Please select the bearing type.

SHG bearing

This is a highly sensitive bearing with excellent rotational performance.
The products were carefully selected by hand from a crowd of other bearings.
Rotational performance is superior to HRCB and nothing can match its ultimate smoothness.
It is ideal for highly sensitive reels that are challenged by sensitive tackle.

HRCB bearing

The new technique that metal itself is hard to get rusty very much by special manufacturing method is adopted.
The bearing is resistant to salt water, and the derusting performance is more than ten times compared with SHG.
It makes rotation feel like silky smoothness that's quite unique to HEDGEHOG STUDIO.
Also it helps tough fishing situations that require both rotation performance and durability at a high level.
This is the next-generation anti-rust bearing for Saltwater anglers.

How to choose bearings

SHG bearing

For freshwater fishing such as Bass/Trout fishing which attaches importance to sensitivity by using light weight lures

HRCB bearing
For overall saltwater fishing which attaches importance to anti-rust effect.
Although you can use SHG bearing on saltwater fishing, HRCB bearing is more suitable because of its durability.
