The CVT ROLLER is affected by the engine speed, the speed gradually increases, the roller is subject to the outward centrifugal to overcome the force of the big spring, along the chute to the outer edge of the disc along the radial movement, the force of the axial movement of the disc increases, the working radius increases, the diameter of the driven disc decreases, thus changing the rotation ratio.
