Froome's Acceleration on the Bike ??

I stated this earlier, either here or on a different Clinic thread.

Froome, from the looks of it, probably had a motor in his bike, the same one Armstrong and Cancellara used at different points in their career.

During the initial acceleration on Mont Ventoux, it seemed as if Froome couldn't keep up with the cadence, then settled down and got in sync with it.

The change in cadence was just too ridiculous to have been caused by anything else. And in all my years of watching cycling races, I've never seen such a thing. Only then and only with Froome.

This clip is really good as it repeats his accelerations.

I,m certain RR answered Horsinabout's question about whether or not he had heard rumours about Froome using a motorised bike. RR's post then disappeared when I went back to re-read it.

In a word...

Bike with Engine

RAI footage with David Cassani of motorised bike. Froome does seem to push at the same place on the hoods as in the clip.

 

[Dear Wiggo]

The acceleration does not look ridiculous to me, at all. Edit: ok from a performance point of view, it looks extraordinary, but not like he can't keep up, or whatever the theory is.

And his hands did not move from the tops when he accelerated for a number of seconds.

 

[Almeisan]

I don't see a mismatch between cadence and acceleration. With Cancellara it did look very odd. I don't know if in the case of Cancellara it can mean he has an electric engine in his bike. Seems very easy to discover as well as rationalize internally.

at 7 seconds his right hand clearly moves to the top of the hood...and again at 2.06.

Interesting, but I don't think that it's relevant.

 

[kingjr]

I accelerate like this sometimes on steeper gradients... on a much lower level needless to say...

That's because he's shifting his gears

Cheating b@st@rd! They should not allowed riders shifting gears in last 20k. Too dangerous for threads like this getting started.

So which one is it?

 

[Ney the Viking]

Oh no, not this motor crap again ... It was rediciolus with the Canc and it is rediciolus now.

 

[sniper]

why is armchairclimber's post being fully ignored?
In another thread he said the Guardian will soon be running a story on Froome's 'o-to' motor. Something about humiliating Murdoch, and leaked designs.
Was that a joke? didn't sound like it.

 

[McLovin]

I think Ventoux attack looks ET only for guys who never rode a bike or use their bikes to go to McDonald's. It was an acceleration, great one, Ullrich like style, but if you look at the images you'll see a fat out-of-form Contador still 15 meters behind even after one minute.
For me this one is far more impressive.

It was a joke. o-to as in O2. Oxygen.

I had a discussion about engines in bikes with two cycling friends, both aircraft engineers, following the Beijing Olympics.

I was met with incredulity. Told that it would be impractical due to weight issues, more so for a three week stage race with mountains.

Well I think what you do is make it lighter (Formula 1 technology?). This may reduce the effectiveness of any electrically powered device, but sufficient to add enough of a kick to what we witness with Froome's attack You can also compensate more by making the rider as light and as powerful as possible, Froome enter stage left!

Then as it is impractical for the whole of a three week stage race, you use it at choice times, like on Vonteux, to accelerate away.

And in the videos you can see the technology is available. So should we put 2 and 2 together?

I have heard no rumors of Froome using a motorized bike, did not write a post about it so it nothing disappeared

.

And I have never read such a ridiculous thing

thanks Netserk.

I actually went to check what an 'o-to' engine could be, and found this:

apparently also applied to bycicles (scroll down)

The chic can be ridiculous but sometimes you should read your own post.

Zam where have you been?

Ps where can I buy one of those bike motors?

 

[Cyivel]

He definitely had a motor, no doubt about it whatsoever.

 

[Zam_Olyas]

I have been travelling and still away....sorry i cant tell you where to buy those kind of bike motors , ask davide cassani maybe he knows.

 

[coinneach]

Actually, what these clips show is how naive Froome is as a rider
He's in the small ring, and worried about shipping his chain if he shifts up.
Answer: don't be in the small ring!
