A set of pulley body and special ramp plate. The angle of movement of the weight roller inside the ramp plate and the position of the inclination are uniquely designed for each model, and the maximum speed is increased to the V-belt limit, which could not be achieved with the stock ramp plate, and at the same time, a sharp start-up acceleration in the low speed range is realized. The roller grooves of the main body are finished with fluorine coating.
