una0004 's Japan Review

If you use L-shaft carbon, you can't go wrong with this.
It won't even come loose unless you have a lot of trouble.

It is a part that makes you wonder why L-style does not offer a product equivalent to this one.

It prevents the shaft from loosening, thus reducing stress.

Used on carbon el shaft.
In fact, it is not loose at all just because it is less likely to loosen.
I feel like I have to re-tighten it 1.2 times per 1leg.
Also, I personally feel that the flight has changed, so I wonder if it is heavier.
