Looking at the photo closely, it appears that the BB shaft broke off
flush; there is no stub visible.

I take it back, partially. I still think it may have been a break,
but the lack of a visible stub isn't dispositive. Looking again, the
crank appears to be a DA with an integral shaft/right crank
design...and the right crank is hanging off at an angle. That would
account for the lack of a visible stub, regardless of whether a shaft
failure was involved.

Break or not, the whole thing came apart when the left crank came off.

Yeah, but don't these cranks secure the BB part with the left crank? ie,
if the pinchbolt came loose, wouldn't the right crank plus the BB slide
out to the right?

There doesn't appear to be a visible stub sticking out of the *left*
crank, though. That suggests no break. Seems to me like the point of
greatest stress in a BB spindle is where the support of the bearings
stops, in whatever form that support happens, so it would have at least a
little stub sticking out.

Definitely. I didn't actually notice that that disc that's hanging
horizontally on the chainstay was the right crank.

Well from what I see the spindle broke odd because the chainwheel and
right crank are hanging on the chain which its held by the front
derailleur. I don't know what sort of cranks these are but the
spindle is out of the BB attached to the right crank.

What event is this?

Everyone must be looking at a differetn picture from all of the
different comments. Its the Vuelta, Stage 2. The crank is a Dura Ace.
Team is Discovery Channel. They use Dura Ace cranks. The crank
appears to be several feet from the bike on the right side of the road
by the white line. Not hanging from the chainstays. The bike and
rider are in the middle of the road. Most likely the team mechanic did
not tighten the pinch bolts on the left crank arm. And the right crank
arm and bottom bracket spindle slid out to the right because the left
crank arm keeps the thing together. I suspect the rider noticed the
thing feeling odd and unclipped the pedal with his right foot. Pulling
the whole crank arm off to the right in the process. And leaving his
left foot still clipped to the pedal and the left crank arm.

Mechanic error. Even superior quality Campagnolo parts might possibly
let the rider down if the part was incompetently installed or adjusted.

I disagree. The scaling is consistent with the crank assembly being
tangled in the chain on the right side of the bike. Plus, there's no
shadow on the road under it; it can't be on the ground. I suspect
that it was lifted when the rider stopped and tried to unclip, and it
fell into the resulting position when he got loose from it.

Check the shadow - the crank is not on the ground, but on the bike
(how, I don't know).

The torque settings on this crank are rather specific. It's impossible
to tell from this angle if the crank pulled through the BB (spindle
intact) or if it cracked in the left crank and pulled through.

I'm surprised shimano hasn't specified some sort of star fangled
nut/top (side?) cap assembly to avoid liability from this sort of
mistake (ie, the crank cannot pull completely off if the pinch bolts
aren't sufficiently tight).

Go for the hit batter. Talk about greased tapers being the devil to
catch, particularly if they get into the water.

I'm with Russell on this. The reason you don't see a shadow is because
the sun is directly overhead...look at the shadow under the bike and
rider.

Just because folks want to believe it sheared off doesn't make it so.

If the crankarm is tangled on the right chainstay, then the pedals
would be about the same distance from the camera. The rider holding
his left foot up is the same distance from the camera as the right
chainstay area. Yet the right pedal is clearly smaller in the picture.
Indicating it is on the right side of the road many feet further from
the camera than the bike and rider and left pedal.

Plus, there's no

There is no shadow because the sun is to the right upper corner of the
picture. The right crank has the edge of the chainring facing into the
sun. And the side of the bottom bracket tube is facing the sun. The
edge of chainrings do not have enough area to cast a shadow you can see
from many feet away. The side of the bottom bracket tube casts a
shadow but it is hidden from view by the solid Dura Ace chainrings and
the fact the chainring is many feet away.

The right crankarm assembly is resting on the ground. Look at the
angle it is propped up. This is the angle you get when the bottom
bracket tube that sticks out the back of the right crankarm is resting
on the ground and the bottom of the big chainring is resting on the
ground. Look at the angle of the right crankarm. Its tilted back
because it is resting on the end of the bottom bracket tube that is
permanently welded/glued to the back of the right crankarm.

The crank is obscuring part of the cassette and the right chainstay,
it's not on the ground. There is no rear derailleur visable. There is
no chain visable.

Looks to me like the right side of the crankset is tangled up in the
chain so tight that it pulled the derailleur way out (broken off?) and
got wedged in between some spokes and the chainstay.

Hard to tell if there's any bit of the pinch clamp remaining on the left
arm but it could have broken near the attachment and then come
completely off out of the photo.

You are correct - It is not on the ground. The telling point is that
if you zoom in, the left side of the chainring is in a shadow (the
bike. You can plainly see that the bike is many feet from the white
line and there is nothing else to cast a shadow.
