I believe that it's possible that Ryder's back wheel maintained a portion of it's angular momentum

thanks for the effort.

indeed, so you agree that it's also possible that it did not maintain any momentum.
i think you were a bit quick to throw that theory out of the window in your first post.

cheers.

I think I admitted (and I certainly do admit) that it's *possible* that Ryder's bike had a motor. My contention is that it is not the only, nor most plausible, explanation--hence this video (taken on its own) is not evidence that Ryder had a motor which makes this a non-story.

this is what happens when two wheelers with real motors crash and spin: https://www.youtube.com/watch?v=-IzEdK7ARg8

Now that is an awesome clip. Makes us cycling fans look like a bunch of amateurs though. Just imagine if Hesjedal and Froome got tangled up in a crash, and then their bikes began to tango in the above fashion—on The Avenue des Champs-Élysées in front of the whole world! :eek:

Now that is something I would pay to see. Although I can imagine it would only be a short while before someone chimed in about how it was only proof as to the rolling efficiency of the newest Pinarello/Cervelo.

Anyone remember this classic finish line stunt?

Except for the fact that the bike hits the barriers, it does pretty much exactly what Ryder's bike does.

Shirley you jest. That's not even close, and waaaaay far from "exactly." :cool:

My first post in the clinic...

First off, don't be such a stranger around this forbidden and dark place. There's always room for reasoned and scientifically based input. Merckx Index's consistent input being a shining example of that.

GoodTimes said:
I appreciate dry humor. So, when I read the first few pages of this thread, I was sure that it was a brilliant satire put on by the clinicians of themselves-- "No way they actually believe what they're writing... this is a big joke, and a funny one at that."

However, it has become clear to me that a majority of the contributors to this thread actually believe the tripe they are writing.

I'd like to finally address this recurring sentiment once and for all.

I think what eludes many people who read The Clinic (and this thread in particular represents one of the starker examples of what I'm hoping to explain) is that is quite possible to express dry humor, reasonable skepticism, scientific analysis and outright mockery of oneself and others...ALL IN THE SAME POST. :D

In other words: The Clinic is not as Black & White as some would like to paint it. This thread is full of excellent humor, excellent analysis, reasonable discussions and absurd ramblings. What's not to love about that? The trick is to try and engage on all platforms. I don't see anything wrong with that, and I can easily wear different hats from post to post, or within the same post. Such an approach makes the forum more colorful, in my opinion.

That's why I am always opposed to those who attempt to curtail such discussions. One never knows where topics like this will lead. And the more unpredictable, the better, as far as I'm concerned. :cool:

As to whether or not Ryder's bike would have had to have been in "reverse" in order to move in the direction that it did, I present Exhibit A:

https://www.youtube.com/watch?v=9UtgFyqoaro

Motorcycle has left side down against the road (as was the case with Hesjedal).

Motorcycle spins COUNTER CLOCKWISE (as was the case with Hesjedal).


So...

So when I originally posted my comment to the Canadian Cycling web site I also sent an email to Steephill TV asking what they thought and if anyone else noticed what I did...Then I just forgot about it...until I got an email back from Steephill with a link to this thread....this is Great..Innis&Gunn....this is fantastic...Innis&Gunn.....

Oh can I mention that a doctor friend of mine said he heard that...Alcheator Dopador has motor mechanisms implanted in his knees that assists in the pedaling motion...I'm hoping he'll have a similar crash to Ryders so we can all see Contador spinning on the ground with his legs thrashing away....Haaa!
Sorry for that last one guys but I've got bigger threads to conquer....time to put my tight pants on! Destroying the peloton one cheater at a time!!!

I found this article, no news there, but the comments below was pretty interesting.

http://cyclingmagazine.ca/sections/...al-crashes-dash-stage-win-hopes-comes-runner/

Commentator notes: So when I saw the crash live something struck my eye as peculiar with Ryder's bike when it was on the deck just prior to the motorbike running over the back wheel...so I went back and watched it again in slow motion....
This is what I see...his bike is completely 100% stopped...no movement....somehow his bike begins moving in a semi-circle and accelerates in that motion until it is run over by the camera bike!!!!! What?? this is absolutely impossible without some sort of artificial propulsion!!!

Video here : http://www.steephill.tv/players/you...hboard=vuelta-a-espana&id=OBvgUBpJSkk&yr=2014

I am no physicist and have no idea about these things, but it does look odd, or am I being clinic cycnic?
Click to expand...

It looks ODD, ODD, ODDDDDDDD. Including the position of the handlebar, possibly just pushing down the right bottom. Pedals, chain and wheel seems to spin as for a BB located motor.

What about potential energy? He is on a slope. Could gravity have caused the crank to turn? He would have been in a big gear. TV is not a great place to gain perspective on the terrain or grade. For the bike to turn there has to be some form of kinetic and potential energy to transfer to motion. We can assume reduced friction too, evidenced by the sudden loss of traction. the pedals may have better traction than the tires?

Have you considered my conservation of wheel energy theory, posited on pg 27? I didn't write it down, but I have considered gravity. I think it would have a negligable affect, but contribute positively a small amount to my theory.

If Ryder is/was using a motored bike, why would he even go into a break? Just use it on the final climb, adios :p

Nothing in cycling would surprise me, but this seems just ridiculous

Maybe JV planted there without Hesjedal's knowledge.

JV was perhaps then planning to activate it remotely in order to boost Ryder's confidence and get him back into his GT-winning mindset.

The crash interfered with the technology though, and chaos ensued. We can see how disoriented and confused Ryder was by the unpredictable spinning of his bike. He could barely catch the thing!

I'd say that if JV doesn't join this thread to dispute this hypothesis, then we have every right to assume it to be true. :cool:

Interesting that Maxime Bouet retweeted the L'Equipe article.

Have you heard of Betteridge's Law of Headlines? It says that "Any headline which ends in a question mark can be answered by the word no."

To c+p a quote from Andrew Marr: "A headline with a question mark at the end means, in the vast majority of cases, that the story is tendentious or over-sold. It is often a scare story, or an attempt to elevate some run-of-the-mill piece of reporting into a national controversy and, preferably, a national panic. To a busy journalist hunting for real information a question mark means 'don't bother reading this bit'

Both L'Equipe and Marca independently use the question headline format because they both know that the story is crap but still want to draw in the rubes.

Of course, but it's still acknowledgment by mainstream media, which is new and relevant to the thread.

It's a moot point.

The crank does not turn.

The bike turns.

im not sure u can say for certain the crank doesnt turn. assuming the back wheel turned maybe 1.5 revs before the bike was run over then in a say 53x11 gear the crank would only rotate about a third of a rev which from the footage is hard to disprove

In France or Spain? Hardly worth the bother.

Really, if you see a headline with a question mark, no-one at the paper believes the story. And they know it's too dumb and inconsequential to get sued for. It's click & retweet fodder tailored for the wilfully dim.

On the contrary. We have a clear view of the pedals.

@ 0:12 Ryder unclips

by 0:14 the bike has rotated nearly 180º but the pedal still has not changed position. The view of the pedal is blocked by the moto's mirror after that point, but up until then, there is clearly NO movement of the pedal position.

Clicking through frame by frame only confirms this.
