New crank concept

We saw and tested these new cranks at Veloswap. These are the "rotor" system setup that claims to eliminate the deadspot in the top and bottom of the pedal stroke. This accomplished by having the cranks "roll forward". Notice in the photo that the bottom crank is straight while the top of the crank is canted forward. Seems like it will work. At a grand a copy, it won't work for me......yet.

Also, that is the top of Aaron's head in the photo!
