At any rate, i think a racer can also benefit from this tech..

From looking at my crankset, (I have two biopace sets)
The chain rings defientrly increase in diameter at the stronger part of the pedal stroke, not the other way around.
Then someone has clocked them differently than they were intended. In your pic above, the small ring has been clocked one bolt hole off as evidenced by the small tab that should be aligned with the crank arm.
You don't understand a lot of things, but you go on giving advice as if you do. What cadence do you think is efficient? My most efficient cadence is between 93-105rpm for road riding
