Since what was in the kit was the same weight as genuine, it was purchased for adjustment,
It is cheap in the set of 6 pieces, and since there is no back side of the thing of the KN project, it is ok if there is no mistake in assembling.
We can sort out because the weight of the actual manufacturer can be selected finely. The friction coefficient required for the shift-up / down roller movement is stable, and the shift rotation speed is stabilized.
Since the weight roller became irregular and the acceleration became worse
I replaced it with 5 g × 3 and 6 g × 3.
Smooth shifting and acceleration became better.
Because it is cheap, I will exchange regularly.
