I watched as this guy, almost finished with a wheel build, grabbed the rim like a steering wheel and pressed the axle firmly to the floor. There was a chatting bonging snapping sound, and the wheel became a shallow taco. It appears to be his first build.
What exactly happened? was the spokes too tight or too loose? How do you avoid this?
I would cry if it happened to me.
btw: the rim was relatively low grade and you can see a seam at the joint.
Thanks in advance for all your input
