Just looked up the rim & looks like 1400N which google tells me is 142kgf. Think I need to up the tension!
Cheers all for help

I can’t decide exactly what angle to come at this, but 92kg (920N) force doesn’t sound like a lot. So assuming you laced the wheel 3-cross, at some point you’ll have two roughly parallel spokes vertically sharing the load. Pretty sure that means 180kg completely unloads the lower spokes. Let’s say you and some cargo onboard come to 120kg, it doesn’t take much of a bump in the road to completely unload the spokes and they start to come undone.
It’s not that simple because the tensile spoke loading and the hoop stress in the wheel is far more complicated than I’ve made it out to be, but I think it’s not far off in numbers.

I think your rim will be a Ryde Andra if it’s stock.
Afaik 2.3mm is 13g, and I agree with Jon - it sounds like spoke wind up / false tension so your wheels are at much lower tensions once they’ve settled themselves. Have had it happen to me before (with front and rear wheels) built with 13g and 14g spokes -in combo with not being mindful enough of removing wind up during tensioning
