Someone should have paid attention in physics 101.

I wonder if he really believes his own sales pitch.

So stupid it's funny. A good read are the comments accompanying the pitch.
-
What is almost more amusing is that one purported associate professor claims that a higher moment of inertia and flexibility in the cranks are advantageous over light, stiff cranks. I think I will go patent my springs attached to a lead disk crank now.
Another study with a small allegedly randomized trial on the Z-cranks own site shows no discernible difference between these and run of the mill cranks, but in somehow still concludes they are better?

Either the guy's stupid (failed physics class?) or a scammer.

No doubt the professor referenced was a professor of METAphysics. According to a commenter at BikeRumor, the turd selling the cranks was banned from Kickstarter after trying to sell the same thing there. Sadly, it appears that people have already sent him money for this latest sales gimmick.

Nothing new. Those types of crank arms have been around for a hundred years or more.
Campagnolo and Cinelli both experimented with them.

Old TA style track crank:

They were a fav of some of the TT and track riders, back in the day.

Must have worked if the Brit TT guys used them. 1981 and those are Cinelli clipless and the rear wheel is radially spoked on both sides...just to throw in another idea that can't work.

I am more impressed by their "happy butts" saddle.

Don't let alien see those!!! I can hear him ranting already!
Think of the speed, power AND comfort you would have if you combined a 'Z' crank with a happy butt!
"Let you have a happy butts" and "Let your private parts ride happy"
Those have to be the best marketing slogans of 2013!Defy physics and do it in style and comfort.
