No one's hating though...
In the 90's Shimano brought out Biopace elliptical chainrings - the idea being that when you are pushing down on the cranks it is effectively a bit bigger (i.e. higher gear) than when they are in the dead spot in between pedal strokes.
The theory makes sense but I thought it was proved pointless and they had died a long time ago - I guess not!
@obee1 "we use kilometres" - great correction, as we all know this makes them significantly closer together
Noone will ever make this because the number of people who will need/buy one will be tiny.
OK, so what problem does this actually solve? Oh that's right, nothing. Trying to be clever just for the sake of it. About Us
