@simonhi- Did you use spoke prep on the threads? A lack of spoke prep can cause nipples to unwind quickly.
Another possibility would be a lack of stress relief. If you don't seat the nipples completely through stress relieving they can go slack.
Been a while getting back to this one guys, can't seem to stay logged in on an iPad for some strange reason ???
Anyway, in response, spoke prep way a little dab of oil on the spoke threads and nibble / rim hole interface. Have always done this and had no problems. I am loathed to use a thread locker as I think that a well built wheel should not need to be chemically held together.
Stress reflief was not required since there is no spoke wind-up (I used CX-Rays). I did use a spoke punch to properly seat the spokes in the spoke holes on the hubs but then this too is just a tap to confirm that the spoke is home.
Simon... we need to see the pertinent details of the build and the rider. Spokes (and #), hub dimensions, tensions, lube, building procedure, rider weight, etc.
Yes, something isn't right... but it could be caused by a lot of things.
Build is 28 hole 3 cross front, and rear DS and Non-DS, the same as my Ambrosio Nemesis with the same hubs. Rider (Me) is 210lbs, not what I would call strong, max power output 350watts, avaerage over a 4-5 hour ride is 160-175W. More a masher than a spinner, average cadence tends ot be 80-85 ish.
Spokes were CX-rays, tightended front to 110kg, rear DS to 130kg. Hubs are Royce Mid flange front, Nemesis rear (Campag).
This is the third wheelset I have built with the same hubs, first two used Nemesis rims, one set has CX-rays, one set has DT Competition. Neither wheelset has moved since the day built them, accept this set where I have used Archetype rims.
I know it is not the rims, since there are so many good things being writtem by wheelbuilders and users of the rims alike.
I can only think that maybe the wheelbuild was a bit sloppy and not quite right, I don't think the drives side could have been any better and in fact it was the Non-DS spoke that loosened.
Maybe I did not have even spoke tension on Non-DS ???
All advice is good advice, especially from those that have built a few good sets of wheels and maybe encountered the sam as me.
Many thanks guys.
