Re:

Not often Google produces no results as it did with this. Looks interesting, is the idea that the springs give an extra boost?

I've seen some of these before.. The idea of the spring was to remove the dead spot in the pedal stroke, so it is a sort of boost I suppose. I guess it's at the expense of rotating weight though.. and I wouldn't like to clean the mud out of the drive side after a dirty ride!

Cool cranks nonetheless. GLWTS
