I'm no engineer, so I probably don't belong here, but wouldn't you need to find the point in the arc where torque is maximum? Couldn't that just be a hundredth of a second, or less? The original post was about MAXIMUM torque, wasn't it?

Bike designers and manufacturers have had engineers looking at the same principles and came up with something very similar to what we're all using now, which came along in the 50's.
