Breaking handle post

About 1.5 hour ago, the handle post was broken.
I felt down for many times, at all that time, the handle touched to the ground and the gravity and my weight were on it.

 The middle rectangular tube flair just a little. The idea of adding the handle to this position is mine. I can say now that's bad idea.

These shifters and brakes were scratched by falling down.
I should change the idea about handle, brake, shifter.
Original is quite reasonable, now I get it.
