Spontaneous spoke failure -- retraction

Post by Mike Elliot » Wed, 13 Sep 2006 06:26:47


A few weeks ago I posted about how a spoke on my wife's road bike
spontaneously snapped at the point where the spoke met the ***. This
started a long thread about defective spokes, and which eventually
devolved into a technical pissing match replete with name-calling.
Tut-tut, I say. Let's show some manners! We are cyclists, the gentlemen
of the roadways.

But, in the spirit of full disclosure, I must confess that I hadn't
investigated the problem more fully. For if I had done so, that whole
regrettable mess might have been avoided.*

Had I been wearing my reading glasses when I was studying the wheel, I
might have noticed that the spoke was intact: it was the *** that had
failed. Split in half. The nice young man at the LBS pointed out
several others that were also splitting. "Aluminum ***s," he said.
"Salt air tears them up."

I blamed innocent spokes and feel terrible about it.

* Of course, the accurate description of the problem may very well have
simply started a different, equally acrimonious, pissing match.

Ok, so let's reset and restart a long thread flaming defective ***s
and a technical pissing match replete with name-calling... :)

Actually no. Among the very few things that are generally agreed around here is
that alloy ***s tend to fail prematurely and are more trouble than the weight
savings are worth.

I recently replaced all the ***ss on a pair of wheels. Tedious, but not
difficult with a cordless driver.

Outside of this group it's usually noted that cyclists tend to be wound a bit
over tight.

And there we have it. Due to my carelessness, a pointless flame war was
started. I must make amends.

Beware the cordless driver.

I like a good dustup as well as the next fellow, but don't start one
just because I can't tell a *** from a spoke. Even with a flashlight.

Not at all.  The point is that the failure occurred while the wheel
was stationary with no external input.  That the spoke *** failed
has no bearing on the failure mode, that of a growing crack under
constant load.  From your description, this was not a wheel that had
been parked for weeks in a caustic atmosphere.

I propose the salt air is a dodge.  The strength of aluminum ***s
being poor, they are loaded near yield and easily fatigue by cyclic
loading as a wheel typically generates in its spoke complement.  I
think you had a fatigue failure much like one that occurs in spoke.

I sense that urination is from people who don't want their religious
attachment to myth and lore of the bicycle to be disturbed.  You
should note which of the respondents are on a verbal jihad, not
addressing the subject but rather attacking the bringer of bad news.

flaming defective ***s

Sounds like a good name for a band!
