pealling push up push down

I still don't know what you are talking about. Whatever is the "most powerful style" may vary between riders, depending upon the type of riding they do (track sprinter vs time trial specialist vs whatever). PowerCranks doesn't prevent any rider from doing their thing as long as they completely unweight on the back half of the stroke.

Just wanted to see if it was possible to change the title to this thread which has always driven me crazy but, in my laziness, I never tried.

Who cares about pedaling "style"? Unless you're a pro with time to spare for training, your time is best spent getting "fitter". This all seems like a bunch of nonsense. Much akin to a "forest and the trees" discussion.

Seems to me the evidence might suggest that form makes a huge difference but, as this thread has demonstrated that is somewhat debatable. Do you have evidence form is of no consequence? Love to see what it is.

dkrenik

What evidence is that?

I didn't say that. I said that given a choice as to whether to work on fitness or form, I would choose fitness as my time for training is somewhat constrained. If I had more time to train I might consider working on "form" (however that might be defined).

Well, as mentioned earlier in this thread. Two recent studies looking at PowerCranks would be some direct evidence. The main thing that PowerCranks does is change the form of the cyclist to something that most would describe as being more circular. The Luttrell study demonstrated a 10% improvement in cycling efficiency in trained cyclists in 6 weeks and the Dixon study demonstrated an 11% improvement in cycling power, again in 6 weeks and again in trained cyclists (plus they also reported an increase of VO2max of 15% in the same time). Unless one is a rank beginner is it unlikely one can see those kinds of improvements from fitness changes or anything else in that kind of time period. Check out the recent thread entitled "poor man's PowerCranks" for a further discussion of this so it doesn't have to be repeated here.


Why not work on both at the same time for maximum benefit? (see above) Everyones time is limited, even the pros wished they had more time for training.

You are correct, for you working on fitness will give best results. It's not a matter of working on "form", it's about discovering a completely different way of applying power to the pedals and for this you have got to know what your objectives are, otherwise you are wasting valuable training time. For time trial purposes the difference between the perfect TT style and normal pedaling (stomping/circular) can have the same effect as the difference between the old high jump style and today's Fosbury Flop technique. Take a look at the video "The mysterious cycling champion",then you will understand. With this technique when you hit the open road, you slip into a higher gear and set your muscles to "cruise control".

I don't know if it's been mentioned here before, but here it is:

Incidentally, I met someone at a race last weekend who swears by them (not that it proves anything of course).

While you say it is a small percentage, what do you do with the PC's that are returned after, let's say, eight months of continuous use during trial period ?

Fday

We use them per our needs. If someone asks and we have a used pair lying around we will usually sell it at a discounted price, usually $600 for the basics, what they usually go for on Ebay, except this will have a warranty.

Easy answer here, do you hurt somewhere during 2hours and more?

I just went through the first 10 of 16 pages and only found that the studies you quote are, at best, "dubious".

Let's say a person applies max force to his pedals in the first few pedalling strokes during attempted max acceleration from a seated 'standing start', what percentage of this max force will he be applying to the pedals when he is still accelerating at a cadence of 80, 90 and 100 ? Has anyone got the answer.
