Quoted message said:Quoted message said:It's certainly possible that the way it was fitted has contributed to
the failure - the top mounting doesn't look anything like rigid to me,
and movement there would cause additional stress. It's also possible
that the failure would have occurred anyway, of course, as the load
exerted by panniers on the dogleg stay stresses the weld in a way likely
to cause early fatigue failure - joint construction that would be
adequate for a straight-legged rack may well not suffice with this
design.
It's never moved, I think that's rigid enough!
I'd be suprised - it's more likely that it does move, but returns to
rest in the same position. Were the stainless straps that contorted
when you originally fitted them? Although I can't quite make out the
bracketry at the seat stays it certainly looks as if it would allow more
movement than is healthy.
Quoted message said:THe first weld went in 5
minutes with weight on it, the second after 400 miles and 10 days of
touring. If it was due to ill fitting, surely the second weld (same place,
opposite side) would have gone as immediately as the first? Surely the extra
stresses would have brought this to light far quicker.
If it failed that quickly it's most likely a bad weld - the fact that
the second one didn't fail sooner does suggest that if they'd both been
as good as the second then the failure wouldn't have occurred.

I'm also still amazed that he didn't mention *to me* that it was ill-fitted
when I was in the shop. Smells fishy to me, it's as if this is a "get out
clause" they use when someone threatens court action.
It sound as if this particular manager realises that he shouldn't have
acted in the way he did, and is starting to squirm.
