Exposed are the hazards of sleep deprivation!
I
meant to say John Marino, Founder of RAAM and the UMCA. He is one of the most inspiring people I have ever come to know personally. I am embarrassed that
Dan popped out of my fingers.
Likewise, I will blame sleep deprivation for not quickly recognizing that PowerCrank is not PowerCAM, the device I was referencing which changed the circular pedal stroke to an adjustable, elliptical stroke. It was marketed in the early 80's. A few Triathletes used it for a bit. The mechanism was to add a cam to the shaft element of the bottom bracket
and match it with an altered crank to produce the eliptical stroke. It was extra work, money and weight. Shortly thereafter Shimano released their eliptical chain rings, a much simpler solution, which put the nail in the coffin... or so I thought until I saw your post.... My bad.
PC's get mistaken for a lot of things they are not.
1. They are not the new "biopace".
2. They are not the same as PowerCam or RotorCranks
3. They do not measure power.
Anyhow, I am going to have to remember that sleep deprivation thing. I generally blame my "slips" on my greatly advanced age. If I can remember it I will try to use sleep deprivation once in awhile to mix things up. If it is really bad I may have to use them both :-)
