Fday said:No, when the lightbulb went on I tested them on myself to see if they might work. When I saw the improvement I then went to a local swap meet to see if I could recruit some testers. Got about 6. And did regular Conconi testing. Few rode them exclusively and only two subjects actually continued on them to the point that they were able to complete a Conconi test using the PC's to compare to their pre PC conconi test. Both of these subjects saw substantial improvement (260 to 380 watts for one in 6 months and 440 to 520 watts in 9 months for the other). Several of the other subjects saw typical efficiency improvements at low powers in a few months (higher power at the same HR) but were unable to get to where they could get their HR up to their previous max and they quit because we were doing this during the racing season.
Anyhow, it was not until I had this kind of data did I feel I could honestly market them and make any claims. At the outset, I had no inkling the numbers would be this high.
The question I was hoping to get an answer to was, when you first got the idea, in what area of the pedaling did you believe the power improvements were likely to take place. Also, has any rider used these cranks when doing serious road racing ?
