Spokes snapping at the thread

Yeah, the wheels were built at my LBS, but re-tensioned by myself since, which could be the problem. I think I over tensioned them, and once one spoke went, to much pressure was put on the others, I snapped a total of 7 during the week, the first 5 at the thread, the last 2 at the elbow, which is where I would expect most to snap.

JJ is correct that it was the book I bought from wheelpro, and whether he bangs his own drum or not, its a pretty clear guide to wheelbuilding.

What happened to the hub Paul? I ask 'cause I've a couple of DT rears and, so far, they've been fine. No broken spokes either.Well.....first of all the hub had that problem when it freezes up and disengages, which was rather disappointing in a new bike......then after about 1200miles it just disintegrated inside......sounded horrible!  Replaced it with a Hope ll, which is supposed to be considerably more robust.My last broken spoke must have been on the South Downs randonee when I was taking it very easy on the descents and don't recall any major impacts!You'd think having rear suspension would help avoid broken spokes.....I nver had one in ten years of 'occasional' hardtail riding.

What spokes were they? The base of the threads is the place they'll break from fatigue if they don't break at the elbow first. If they were cheap spokes they may be more likely to break at the threads - poorly-formed threads can lead to stress risers.
They were DT swiss db spokes, I have heard that DT spokes aren't the quality they used to be and sapim are now quite a lot better, so I will probably rebuild using them.

Should be OK. Like I say, spokes will either break at the elbow or at the threads, it's pretty much a toss-up which it is

So you've read some of that book?

all three breaks were at the thread end.

Took the wheel into the shop this morning and the owner (who does know his stuff) was baffled by the fact that three spokes snapped at the thread end.  It hadn't taken any hits this time either.

He reckoned I had the best wheels and spokes possible.  (within reason!)
