Patented features like the free-floating rotor-drive system, rotating swivel spring and infinitely adjustable cam, are aligned to create a more direct transfer of energy that optimizes the stroke for more power and precision. (U.S. Patent No. 6590147B2)

DW 9000 Series Pedals feature an infinite adjustable cam, allowing the pedal to be easily set from Accelerator‚Äö?묢 to Turbo‚Äö?묢 Drive or anywhere in between.

The Free-Floating Rotor drive system allows the shaft to turn independently of the rotor, directing energy from the pedal board straight to the beater. The design also uses friction-reducing ball bearings to optimize the already incredibly smooth, gravity-defying action.
