OK.... all you experts and others..... here a couple of shots of the

Looking at the first pic you can clearly see that here we have to do
with a classical case of metal fatigue

Starting from the top a crack begins to grow and at some moment the
remaining sound material is insufficient to bear the normal
instantaneous load and there you go :-(

The question is how and why such a fatigue crack can develop so fast:

1. base material unfit: too much hardenened
2. surface defects at the initiation of the crack, there is a sharp
notch where the diameter decreases with a step. I guess Look executes
this the same at all there pedals, so keep my fingers crossed.

Anyway: Within the time as stated in your original post this should not
have happened and imho you have a case.

Look as well at http://materials.open.ac.uk/mem/mem_mf.htm
Keep us informed.

See the stress riser? It's undercut right where it failed.

I can't see if it has an inclusion or just dirt but Keo would most
probably settle that, based on "shouldn't do that in normal use". I'm
neither a metallurgist nor an attorney so my opinions carry little
weight here.

You did an axel? really? In midair?

Caveat: I am not an engineer. The failure could have resulted from:
sharp step in spindle causing stress riser and cracking (probably not,
because you would see lots of failures in similar pedals), hardening
problem (you would also expect to see failures from the same batch), a
crack caused by fretting of the spindle by the bearing cartridge,
gouge during manufacture initiating crack, and finally, punishmnet
from God! Except for the last one, the manufacturer is responsible.--

Nice failure picture! As you see, it fatigue cracked about half way
through in the semi smooth area with parallel waves of crack
propagation. Then stress concentration caused by the crack and
limited remaining material caused a forced fracture where typically
grain structure of the metal is visible and rough. Not being able to
see how deep and narrow the groove in the spindle was because the
outer end is not visible from the side, I assume it was sharp enough
to be a design flaw that initiated failure.

http://tinyurl.com/3kunfl

Although I cannot see the internal parts, I take it from reviews, that
it has a cartridge ball bearing at the outer end and needle bearing at
the attachment end. The description suggests the needle rollers run
directly on the spindle, which means the spindle must be case hardened
to give it a crust hard enough to act as inner race of the bearing.

That gets back to the subject of anodizing causing failure in aluminum
parts because a hard crust overlies more ductile material of lesser
yield strength. That together with a notch are killers. I would like
to see both parts of the spindle cleaned and laid side-by-sider with
the fracture facing the camera.

The Keo construction is the opposite. It has a needle bearing on the outer
end and a ball bearing at the attachment end. The look site has a good
picture of the pedals construction.

According to the descriptions I found the heavy load bearing bearing,
at the pedal attachment end, is a needle bearing. Could you give a
URL to the Look site to which you refer? From the broken part photos,
there seems to be no room for a cartridge ball bearing at the
attachment end.

Both Look (one) and Keo (double) have cartridge ball bearings near the
crank and a Bremen Cup needle type bearing on the outside end of the
pedal. The needle assembly being pressed into a 'blind' socket in the
pedal body, that end is not simple to service.

Fatigue crack at stress rizer from poorly radiused groove in the axle,
from what I can see.

Look (one) and Keo (double) have cartridge ball bearings near the crank
and a Bremen Cup needle type bearing on the outside end of the pedal.
The needle assembly being pressed into a 'blind' socket in the pedal
body, that end is not simple to service.

According to the descriptions I found the heavy load bearing bearing,
at the pedal attachment end, is a needle bearing. Could you give a
URL to the Look site to which you refer? From the broken part photos,
there seems to be no room for a cartridge ball bearing at the
attachment end.

And indeed once you've waded through their flash, there is a picture with a
ball bearing at the crank end and needle at the other, with text agreeing
with the picture. "There is one ball bearing (10mm in and 19mm out) for
axial loads and a needle bearing in the middle of the pedal to support
radial loads".

They don't make it easy but thanks. That clears up how the bearings
are located. Cartridge ball bearing at the attachment end and a
needle bearing somewhere between there and the outer end. I am
disappointed that they didn't show a spindle with the other parts
ghosted around it so one can see where things are.

OK, Here's some pictures........ Me day of the crash and with the
evolving black eye of the following day. Also CU of pedal & axel.
Note, upon looking at these with the passage of a little time I did
notice the shear is not exactly flush with the crank. But maybe 3/4 of
inch from the crank.

At roadbikeriderreview.com there a three reviews out of 70 of keo sprint and
carbon pedals that have broken axels. That doesn't count the broken ti
axel.

that is ugly !

is the situation accounting statistics?

this grade is best caws of the intended run only 3-4 are scheduled to
snap off ???

itsnot like daze gotta buy 100k shafts, right ?

at $150 to an elite group of snotty tech weirdos you'd believe the
company would afford an unbreakable grade ?

I just cannot imagine my breaking a shaft on the $12 Nashbar bear
trapsbut there you have it...
forearmed is foresworon !

it's "axle".

almost certainly fatigue. this can be either defect, or abuse. absent
pics of the fracture surface, it's impossible to say.

what /is/ possible to say however is that you have a legit reason to
warranty them and/or take up the issue of damages if you are so inclined.

ok, classic fatigue. the question is, what initiated it. how did that
corrosion creep do deep into the housing? did you ever use a pressure
washer on this bike? anything like "simple green" cleaning agents?

inclined to agree. the broken stub shows nothing other than the
possibility of a stress riser at the initiation point. i'd like to
compare the profile with the unbroken axle.

Interesting remark....

Quite some corrosion products visible.


Hydrojetting or even worse acid cleansing agents might 'help' in crack
initiation, though, imho, even with these this should not have
happened.

Sorry, been away a few days. Wow, lots of thoughts and
inputs...thanks..... To answer a few questions... No never used a
power washer or hydrojeting on this bike or the pedals. Usually clean
it with the "Pink" stuff out of the spray bottle and terry cloth
towels. Occasionaly give a big scrub down using dawn... but the hose
is on mist mode for the rinse off. ..... so like the opposite of a
power wash....

Re: the comment on bottom damage to the pedal... not really. Those big
dings happend that day.... I compared it to the left hand pedal and
there is no comparision. That axle snapped and the pedal stayed
attatched to my shoe and went straight down to the asphalt. Wacko...
So what you see is what you get when that kind of thing happens.
