How to identify the optimal bolt length using the bolt length selector.

Insert the adapter fixing bolt into the frame mount area, and make sure that the length of the protruding part is 6.8 mm.
Note:

When using a bolt length selector, make sure that the tip of the bolt fits within range A.
When checking the length of the bolt, do not use a washer.
