Not to highjack this topic, but i just build my first wheel (mavic Module E2 for a classic bike) and when stressing the rim on the floor disaster happened as i pressed thru the rim and now there is a horrible wobble and the rim is gone. No way did i use to much pressure as i'm light build, but where the spokes not tight enough (i used 120/130 kg on the rear).

My main q'n is what was the reason for this.

I have another E2 rim and will start all over, but not knowing what caused this i'm not all to happy to start over again.

Any advice please.
