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.
