Scientifically proven technology that enables athletes to ride harder, longer and faster with less fatigue. By increasing the size of the gear when you push the hardest (downward stroke) and then decreasing the size of the gear to get through top and bottom dead zones quickly. This patented curve enables the force on the pedals to be constantly proportional to the muscular force of the rider.
