This could really become a great crank?

Pretty cool concept, it might just work. Just one thing, the 4 chainring segments still only have fixed diameters. So essentially I dont see it effectively changing diameter.

 

Like if you have a disc of 200mm diameter, and you cut out segments to make it say 150mm. The resulting disc will not be circular, but like a square profile with arching sides.

 

Just my thought.
