DW 9000 Series Bass Drum Pedal

Smooth, gravity-defying action
To create smooth, gravity-defying action, the 9000's Floating Rotor is 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 infinitely 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. Furthermore, by moving the location of the Floating Spring from the end of the hex shaft to the center of the pedal, the vertical alignment of the moving parts is maintained and the indirect transfer and loss of energy is virtually eliminated - further optimizing the pedal's speed, power and precision.

Additional features
In addition to Delta ball bearings at the rocker, hex shaft and hinge, the 9000's also employ friction-reducing ball bearings in the rotor and spring connector while incorporating several of the 5000 Series' most popular upgrades such as a stackable heel plate, dual / side adjusting hoop clamp, 101 two-way beater, built-in spurs and lightweight aluminum pedal plates and linkages.
