How does the bottom bar latch work?

Hi StridaD,

actually there is a small spiral spring in the bottom tube locking to be found.
The outer diameter of the spring might be at 2,5 mm, the groove, which contains the locking latch, is about 3,2 mm. Sorry, canโ€™t tell the length without disassembling! :laughing:

Position 1 (fully unlocked/locked bottom tube):

The spring is pressing the locking latch upwards.

Position 2 (in the moment of locking):

The latch is compressing the spring.

Any other question? :smiley:
