Does a mechanical advantage of increased gearing sound Interesting? If so, read on.Through research and testing of many different prototypes with varying amounts of Ovality we found 115% (from the top centre) to be the optimum.The benefit of this is twofold? Increased gearing on the downward stroke and faster crank speed to get the crank propelled back around into the power phase continually. This is a significant gain because virtually all studies into pedalling performance suggest that a minimum 80% of your power comes from the downward motion. Mainly because much larger muscle groups are used for this motion. The physics sorcery adds extra power in the downwards stroke for no extra effort...
