Power-Curved Cranks FTW!

Note: I have a special spam folder for the occasional gems like this from Taiwan

Power-curved cranks use the design of golden spiral ratio, which create more pedaling efficiency than traditional cranks can provide, so that no matter bike lovers or normal riders can enjoy more fun of speed and comfortable riding.

BioPace redux. Anyone going to the Taipei Bike Show please investigate further. Totally pimp to put a pair of those on a cargo bike.
