As Ray mentions, worth getting (both) wheels rebuilt with quality (DT or
other) spokes.
If its happening at the hub end, it may also be poor fit into the hole-
face of the hub. I used to do one a month on a crappy STX-RC rear on my
mtb commuter
The pulling off from the ights scenario is probably due to the
'torqueing windup' that occurs due to the power transfer from the drive-
side of the hub to the non-drive side. the non-drive side 'catches' up
and gets twisted placing huge forces on hub/spokes (this is all
incremental, mind). Is there any consistency of spoke location/side?
Love to see a 'wheel-building-machine'! Have images of 'Go-Gadget'
contraption with telescopic arms flying all over the place 😄
