Shibata GRK light weight knuckle stopper R31S332

This aluminum knuckle stopper was developed to meet the latest trends in geometry.
By using aluminum to reduce weight and making the body thinner than a standard knuckle stopper, the shape has been revised to further improve the turning angle.
By providing a hexagonal hole on the bottom, maintainability has also been improved.

It can be used not only with the Lightweight Aluminum Knuckle V1 (R31S331) but also with conventional knuckles.
