Data, not speculation Noel. Some of us are real scientists.backdoor said:Yes, each leg's pedalling power stroke gets an extra 60 degrees (entire dead spot sector where your leg muscles are effectively idling) of almost maximal torque application. Rotor cranks could give you an extra 10-12 degrees of minimal torque application and that was only if you got the timing of your muscle action correct.CoachFergie said:5 x more! Very specific statement!! So you must have some data to support that very specific claim!!!backdoor said:One of the advantages claimed by the Rotor Crank inventor was that it gave extra pedalling time per hour of pedalling, the problem with this was that extra time occurred in part of the dead spot sector where minimal if any torque could be applied. Anquetil's pedalling gives more than 5 times more extra pedaling time than the Rotor Crank and it occurs where (with his technique) almost maximal torque can be applied. I am referring to the 'Rotor Crank' not the Rotor or any other type of non round chainring.JayKosta said:--------------------------backdoor said:...
The biomechanics of Anquetil's TT pedalling are somewhat like the Rotor crank idea,
If Anquetil's TT technique was similar to using ROTOR (or other oval) chainrings, then the article mentioned earlier -
might provide an explanation about why it's use has not 'caught-on' as a mainstream method.
