Enve G23 Rear NDS Spokes De-Tensioning

[proletariandan]

Hey y'all,

Has anyone had an issue with rear NDS spokes on an Enve G23 de-tensioning?

I got a used set laced to WI CLD hubs a few months ago.

When I got them, the DS tension (according to my Park TM-1, which is 4 years old but based on other wheels still seems to be relatively accurate) was way high - like 140-150kgf.

I re/de-tensioned to bring the average DS spoke tension back town to 120kgf, which put the NDS spokes around 60-70kgf (IIRC) with no tire.

A few months later, I noticed that a few of the NDS spokes were reading below the chart (2-3 on the meter), which ends at 5 (53kgf). This is with a tubeless tire mounted, but most of the spokes were still at 53kgf per the chart.

I retensioned the rim to even things back out (or to get as close as I could) and now, ~2 months later, a couple of NDS spokes are low again.

Is this rim shot? Is there anything else I can do? I emailed Enve and they just said to bring it to a local shop, which I can do, but wanted to see if y'all had any other bright ideas. Trying to avoid an eventual broken spoke...

Thanks!
Dan
