It is an asymmetric accelerator only for LoopUp.
It is not a mistake to say that it is the most important part in LoopUp.
We use high-strength materials.
If you feel that the fixing force during use has decreased, replace the shaft.
※ There is no need to replace first if you get used to it, but there is a possibility of overdoing it and damage it in the beginning
Please use it carefully in the state of the axis.
