ok, I need a little help. I have probably 700 miles on this wheel set. the rear wheel is the problem. at aprox. every 150 to 200 miles I find the spokes have loosened to the point that the wheel flops around while ridding. I was on it today and just thought I was having a bad day, but I got curious and stopped to check things over and found the spokes were all loosened again. To the point that when I shifted my weight the brakes were dragging! I was able to turn all drive side spokes 1 whole turn and aprox 1/2- 3/4 on n.d.s.
So here's the deal, cpx 33 rim,32 spokes, ultegra hub, dt double butted spokes. I use no prep, I shouldnt have to, never used it before. Each time I have readjusted this thing, I have tightened the nipples till I start stripping drive side nipples. I dont have a tension gage ( waiting on its delivery) according to sheldon that should be tight enough. but 175 miles later they are loose again! I know I could use a thread locker on it, but thats not really fixing it.
If anyone has any Ideas about this I would appreciate hearing your thoughts. and yes they were stress relieved and I took the windup out of the spokes when I tightened them. I am not a complete newb, but this one has me stumped.
