Hello!
I finally finished building my 931 frame!
(Homemade color. I wouldn't do it again!)
This is the initial version of the rear triangle. The bearings are crimped in force. I have hope that the rigidity is given after a few kilometers.
The grommets supplied by Top-fire are not effective.
What do you use?
