the tube measurement is not correct
Color: Black 30.9mm
The diameter measurement of the tube is not correct, I had to sand it to be able to reduce the diameter and be able to mount it on the bicycle.

Well, it's a seat post!
Color: Black 27.2mm
I like the markings on the side. I can lower the seat and then easily put it back at the right height.
