To create incredibly smooth, gravity-defying action, the DW 9000PB Single Pedal has a Floating Rotor that’s not permanently affixed on a conventional drive shaft but is mounted on a free-floating drive shaft using friction-reducing ball bearings. In addition, the patented rotor can be adjusted using the Infinite Torque Adjustment for a variety of positions from center (Turbo-style) to eccentric (Accelerator-style), achieving the desired balance of power and precision in any playing situation.
