Flimsy? (Millars chain)

From Pez:

"...As for the offending chain; upon examination by the mechanics, it
was found to have broken not on the pin, but right in the middle of
the link. That¹s some serious power going through the transmission to
achieve a break like that!..."

Almost sounds like Hincapies broken carbon wheel in PR (a poor
equipment choice IMO) that morphed into a puncture.

No, it's a MUCH MUCH MORE FRIGHTENING equipment failure.

If this is true, then surely the likely root causes were either some
sort of bum link (whether in manufacturing, delivery or installation) or
else they were cleaning it improperly and caused hydrogen embrittlement,
or force majeur.

Has anyone else ever had a chain fail at the link?

I don't think that most of the people here would understand just how
frightening that is to an engineer.

It can happen if the link has been bent and then straightened, causing
metal fatigue. Or if one side pops off the rivet, the other side will
of course break. Maybe the chain was damaged when the extra links were
removed to make it the correct length. It would be interesting to see
where it broke in relation to where the two ends were joined, and of
course see a picture of the actual break.

dumbass,

yes. also he was probably using a "lightweight" chain with holes
punched in the links.

I've never seen a link plate fail. It was always pins coming out of plates that
was the cause of the chain failures I've seen.

Or how frightening it must be to *be* an engineer... :>😉

Yeah, but once that happens the remaining link gets bent enough to
break, so maybe they reported the effect rather than the cause. Better
for the mechanics to make it sound like a manufacturing defect rather
than the more likely scenario of improper assembly or damage during
assembly.

I've had side plates fail, always on a climb thankfully, and
not in a sprint. An interesting experience but it didn't
make me want to chuck my bike off the road.

In retrospect I think my side plates were probably damaged
from earlier shifting incidents of being thrown off the
chainring or cassette.

It could be that Millar's chain was fine at the start line
and he damaged it during the ride and that lead to breaking
it later on in the same ride.

I've worked with lots of engineers. Nothing to it, in fact it's a joy
to deal with rational, smart people. The problems arise when you have
to work with "engineers". I think we can all relate to that. ;-)

That sounds about right to me. I don't care for the pins that Shimano gives you to
assemble their chains. I use a master link - the SRAM ones work fine.

Dumbass -

I've broken hundreds of chains. They broke because the designs didn't
take into account the frightening amounts of wattage I was/am capable
of producing.

As an engineer, I find it very frightening.

thanks,

Kunich Gringioni.

At least you didn't find it unsettling.

Dumbass- you were supposed to laugh at this part:
--The problems arise when you have to work with "engineers". --

But what the hell, a laugh is a laugh. I've been laughing at you,
too, SLAVE BOY. In the news-

Bah- I'm working on a Huffy with dual JATO bottles that will blow the
doors off that Smartcar. I'm having a little trouble getting both
bottles to fire simultaneously -and shut down simultaneously. Also,
it turns out it's critical to get the center of thrust at the center
of gravity... I need to get those videos on YouTube...
