look how you will end up if you dont pedal in circles.

I guess the ancient lore of "ankling" still remains. 'tell ya what: I'm even long since fed up with being preoccupied with cadence. I just twirl the cranks in such a way so as to put a nice, even load on the drivetrain at a comfortable speed, and get a sort of smooth flywheel effect going. One doesn't need quantative numbers on a computer display to achieve that; it's all about feel. When riding during a quiet night with a bottle generator on, the buzz of the generator feeds-back the smoothness of your pedal strokes. When you hear: "tzzt--tzzt--tzzt" instead of a steady hum, your pedaling motion isn't very smooth. As for pedaling circles, it's far easier and more natural to unweight the upgoing backstroke foot, than it is to pull-up on the backstroke while unweighting the pushing-down foot on the frontstroke. Beginning riders' bodies learn this early, and they get over those initial after-ride "spaghetti legs" as their riding muscles learn to cooperate with, rather than fight against each other. That said, I guess it doesn't hurt to practice one-legged pedaling every once-in-awhile, if only just to show off. Well, actually I think one-legged pedaling exercises /do/ help to smooth one's pedaling motion. cheers, Tom -- Nothing is safe from me. I'm really at: tkeats curlicue vcn dot bc dot ca |

I went up that in the small ring to the parking lot above Emerald Bay. From there I went into the big ring and pedaled the rest of the 55 or so miles around Tahoe and up Spooner grade and then back down Highway 50 and back into South Lake Tahoe. I was with some people who were very slow so I was pedaling extremely slowly for a large part of the Spooner Grade climb. Yet I never had any problems at top or bottom centers like I used to have. So I suppose I must be pedaling circles in order to get through the dead spots. But I couldn't tell I was doing that. It felt to me as if I was just pedaling normally. |

It felt to me as if I was just pedaling normally. I think this must be the first time you observed what was occurring. Next time you doubt, just coast for about three feet and continue to pedal with forceful down force. I don't know what dear (cadence) you rode but there is only a small dead zone at the top of the stroke that essentially is coasting for about a foot or two before the downward stroke begins and if also pulling up, the upstroke begins. It does not require pushing forward over the top or pulling back on the bottom of the stroke. Pedaling effectiveness is limited by how much power is delivered to the pedals per revolution rather than how many muscle groups are involved. Therefore, all the artificial non-vertical forces don't create any additional propulsion except in an anaerobic manner as in a sprint. While I understand what you're saying, I was in a 50-19 much of the time even at 4-5 mph and up the steepest part of the climb up Spooner Grade. Granted that the climb isn't very steep and that near the top I got tired of shadowing the slower people and when they were all together I rode to the top in the same gear at about 10 mph for perhaps a half mile. The point was that even at that slowest speed I didn't detect any dead spot sagging. I think you're trying to say that the spot is so short that decent riders don't normally feel it. Perhaps you're correct. In any case, I do pedal circles quite a bit when the road gets really steep and I'm undergeared. Before I used to have to concentrate on doing that but anymore I don't pay a lot of attention to it and simply do it more or less automatically. |

Wrong, effectiveness is determined by the ability to maintain crank torque. This involves all the leg muscles, else the torque will fluctuate dramatically reducing efficiency and the rider has to accelerate twice for each crank rotation thereby using up more energy than with a constant torque. Along with supporting the body, this is what makes cycling more efficient than walking or running. Constant velocity is most economical. It is also important not only to keep the torque through the pedal cycle steady but not to waste energy by unecessarily activating muscles will not contribute to perpendicular driving force of the crank end. Lifting the rearmost leg is superior to pressing down on the foremost because muscles work more efficiently at lower loads. |
