The DW 9000 Series Single Bass Drum Pedal is engineered for drummers who demand a smooth, powerful and highly adjustable playing experience. Every major component in the 9000 drivetrain is designed to reduce friction, improve stability and give players greater control over how the pedal responds underfoot. At the heart of the 9000 is DW's Floating Rotor design, which adds bearings directly into the cam assembly to help the drivetrain move through the path of least resistance. By better accommodating the small variations found in any mechanical system, the Floating Rotor helps create the exceptionally smooth and consistent stroke the 9000 Series is known for. The EZ Infinite Adjustable Cam lets players continuously adjust the pedal from a linear Turbo-style response to the increased acceleration of an Accelerator-style cam-or anywhere in between. This allows each drummer to fine-tune the pedal's leverage, response and feel to match their playing style. DW's Floating Swivel Spring system further reduces resistance by allowing the spring connections to pivot more freely throughout the pedal stroke. This helps the spring transfer energy efficiently while also reducing wear at the lower spring connection. The Delta II Ball Bearing Hinge™ uses dual ball bearings and an interlocking component design to create a precise, low-friction connection
