ankle shin etc) into an immovable object (the stone wall)
In my fucking experience something like this would have happened
before (or as a part of) the pedal breaks off the spindle or the
spindle breaks or the crankarm breaks or the crank rips off the bottom
bracket or the bottom bracket itself breaks.
What makes more sense is that his left handlebar caught on the top of
the wall causing a violent steer to the left that then made a pivot
point of the front hub and launched him face first into the pavement.
(also notice his facial deformation after the crash.)
So the forces at play were the conversion of most of his forward mass
and speed into an arc extending 3ft ish from his front hub and into
the pavement. Violent indeed.
Reminds me of the spill that Bart Bell and Tom Brinker took on the
back of the tandem out in Colorado Springs in 1987ish. I was shocked
to see them alive after that. I can't recall who was the stoker that
night but they were slammed into the concrete in a way that give me
chills today.
PS ( I am not confusing this with the 92 Nats crash)

dumbass,
riders strike pedals on the ground all the time. when that happens it
doesn't break the pedal or crank, it lifts their rear wheel or their
entire bike.
it's not hard to imagine that weylandt clipped that low wall and it
flung him into the opposite wall.
Vagina Gorilla
Dumbass. Which would hit first, his handlebar or a pedal ?
Strike pedal? Like in a criterium ? A glancing blow while
cornering ? Not even close.

Voight had almost as bad an accident in the 2009 Tour without hitting
anything in particular.

Wasn't that road undulations and then he lost control. Much more of a
sliding crash.

Voigt fell to the side and slid a long way, so his kinetic energy
dissipated much more gradually and over much more of his body
(including his face/head). It sounds to me like Weylandt took a much
more sudden, forceful, brief impact to his face/head :-(.
Anton Berlin
Use your god damn brain for a minute.
Consider the forces at play. Where his center of gravity is right
after the moment of a pedal impact and where it goes in the handlebar
scenario.

happened after he hit the wall, it's all speculation. My take is
regardless of what hit the wall, at the speed he was going, it
viciously torqued the left side of the bike. It's likely something
broke off the bike in the process. He probably was airborne before
hitting the pavement, with little loss of speed, and hit his head
either on the pavement or the "other object" (opposite wall?) cited in
the articles.
My only interest in understanding accidents like this one is to learn
what happened with the intent of avoiding the same fate. The lesson I
learned is - don't look back on a descent when you're going 40 mph and
hugging the apex.

I've been yelling at my girlfriend for weeks to stop looking back when
she's riding and just pay attention to her line and what's ahead. I
think she gets it now.
The reality is it doesn't help to look back. There's no accurate
judgment one can make based on what's behind them. I used a mirror
for a brief time and realized that even if I did see a semi speeding
toward me it would be too late to bunny hop the curb by the time I
assessed it correctly.

I find it does help, in making the driver aware that you see him. It
humanises me to them. I feel it often makes for a slightly wider pass or
lower speed.
RicodJour
Of course it helps. Anton yelling at his girlfriend...eh, not so
much.

When falling off a bicycle at speed there are two things to consider.
The force exerted on you by vertical deceleration when you hit the
pavement. This is normally survivable because the vertical velocity
component isn't high even though the deceleration distance is small
(the road doesn't give). This is the design criteria for helmets. The
forward component is the more potentially dangerous and is again
survivable if you slide a few feet. However, hit a wall, tree or other
immovable object and the deceleration is huge and the damage
potentially much more extensive.

I think his left bar hit first and turned the front wheel to a 45
degree angle. Once this happened the front hub became a pivot for the
energy and flipped him head first into the pavement. I've hit pedals
and legs against immovable objects - the energy remains mainly below
the center of gravity and it's easy to maintain bike control.
