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.
If you were stress relieving there is a better way to do it. Grab parallel spokes on either side of the wheel and squeeze them as hard as you can. This temporarily over loads the spokes to their yield and removes the built up stresses.
