Jason of A Road Bike 4U Talking About the ROTOR 3D Crankset with Q-Rings

Independent research has shown a 4% improvement in power, and a 4% decrease in lactic acid and heart rate while using this crankset. The arms are made out of machined aluminum so they are lightweight and extremely stiff. They are available for all bottom bracket configurations.

The Q-Rings are elliptical and have the larger portion of the ellipse in tune with the power stroke of your legs. You can also fine tune the cranks to your riding style.
