No Alex, I am trying to explain what is meant by pedaling efficiency and how much can be gained by improving it to those who believe it's not worth spending time trying to get better return from the force that is being applied to the pedal . What is your definition of pedaling efficiency ?

Interesting about applying to pedal from 1 to 3. So the max you can apply to the pedal is body weight at 3 oclock . Therefore the ideal saddle position should be - whilst on the pedals at 3 oclock and 9 with the bum lifted off. Directly below is center of gravity and you can only apply your own weight to the pedal as all you have is gravity pulling you down....unless you pull on the bars?

This is the position to apply maximal force on the pedals:

The maximum he can apply is bodyweight unless he pulls on the bars.

Uh, yeah, which is exactly what one does in a track start.

More like he needed a wee chat with the mechanic I'd say...

Energy output / energy input

In case of cyclist, that's energy delivered at cranks as a proportion of energy metabolised.

But in terms of importance, efficiency ranks lower than actual power output. I don't care if I am less efficient, provided I can sustainably produce more power ('cause power output is what matters - bike races are not economy drives). If I produce more power because I am more efficient, that's fine too, but it's power output that is the determining factor of what we should focus attention on (physiologically speaking).

Your Anquetil anecdotes are amusing, but irrelevant since they are anecdotal and not supported with any actual data.

To illustrate the one occasion where bodyweight is a limiting factor?

Question was about where in a crank rotation one can apply maximal force - in response to whether that would involve pulling on handlebars. Which is does. So I showed a pic to illustrate.

d87heaven

Yes of course that is the only time you apply maximal bodyweight to the crank, I never stated you didnt or that you had to all the time. But if you are apply weight to the crank doesn't it make sense that your center of mass/bodyweight can be applied to the crank in the most efficient or optimal way ie from your point of balance as what you apply is bodyweight using muscles as to support it. That probably sounds clearer in my head.....possibly.

I never said you stated anything. You asked a question, I answered it. Well at least I think you asked a question - it did end with a question mark.

Please work on your grammar. It's not clear to me whether you are trying to make a statement, ask a question, talk out loud to yourself or something else.

So sorry old boy, don't get so upset with the uneducated. BR doesn't work to well on my Android phone, I'll try harder next time.

You appear to be referring to the bodies efficiency. Pedaling efficiency and effectiveness may not be important in road races but things are very different in time trials. You waste energy taking your idling between 11-1 o'c while with a little extra energy I can apply maximal crank torque there and for the same force that you and I apply to the pedal around 1.30 o'c, I can get double your chain drive power because of my stroke's maximal tangential effect. At a cadence of 90 over an hours cycling this happens 10800 times or to put it another way, over an hours cycling a masher's legs are idling for about 10 minutes, when with correct technique they could be applying close to maximal torque. One-legged pedaling leads to the circular style which can lead to the semi circular or perfect pedaling technique.

Urgh. Is that really the best you can do?

Been watching the track cycling all afternoon, and they haven't stopped talking about the importance of the pedalling stroke the whole time .. jus' sayin'.

I obviously spend too little time on the internet what is a TARD pray tell?

It comes as no surprise that people are obsessed with trivia, and are perhaps unaware of what really matters.

In other news, if only Frank would make an appearance we could have the very first Bike Radar perpetual motion machine, otherwise known as a pedaling technique thread. It really is a circular debate (which contributes little to improving people's cycling performance).

What really matters applies to all sports but having worked 100% on what really matters, it's what you do with the available energy you have created that makes the difference in TT's. Pedaling technique discussions always appear to turn into the old argument of which is best circular or mashing, only because people are unaware that there is a third semicircular technique and there is an ideal time or place for each of them.

I hope you don't coach, pedalling technique discussions should be banned!
