The DW 9000 single and 9002 double bass drum pedals are simply the highest quality pedals made today. This production line series offers a exclusive floating rotor and independent drive shaft along with a full complement of the  innovations and progressive designs as well as the many of the performance-proven features of DW's current state-of-the-art 5000 Series Delta II pedals. Among the 9000 Series pedals' advanced features are: Free-Floating Rotor and Independent Drive Shaft To create the pedal's incredibly smooth action, the rotor is not permanently affixed on a horizontal drive shaft but is mounted on an free-floating drive shaft using friction-reducing ball bearings. In addition, the 9000 rotor can be infinitely adjusted in a variety of positions from center (Turbo-style) to eccentric (Accelerator-style) to achieve the desired balance of power and precision in any playing situation. Free-Floating Spring Assembly By moving the location of the spring from the end of the hex shaft to the center of the pedal, and maintaining the vertical alignment of the moving parts, the indirect transfer and loss of energy is virtually eliminated-- further optimizing the pedal's speed and smoothness. Delta-Plus Multi-Bearing System In addition to DW's Delta ball bearings at the hex shaft and hinge, the 9000 utilizes friction-reducing ball bearings in the rotor, rocker and spring connector. Heavy-duty Molded Pedal Case The 9002 includes a custom-designed, injection- molded case with special compartments for pedals, beaters and accessories.
