Every time one of the spokes lost tension suddenly. It was so out of true that the wheel rubbed brake pad.
Last two happened after hill climb (like 15% grade in one section).

I used Park tool spoke tension meter to make sure tension variation was within 10% range when I trued the wheel.
It only happened on rear wheel. Front has been always perfectly true.

Does anybody encounter similar problem ? I am trying to figure out what could be the cause and how I can prevent this. I would appreciate any input.

Thank you
