The 5000 Series Bass Drum Pedals established DW's reputation for innovation and quality. Now they developed the Tri-Pivot Toe Clamp. The Tri-Pivot features three independent, 360-degree, rotating rubber pads that firmly grab almost any diameter and thickness of bass drum hoop, from the top and the bottom, with zero slippage. When combined with a new, textured, rubber pad on the base plate, there's never been a better system for attaching a pedal to a bass drum. To improve on the top-flight smoothness and feel of the 5000 Series pedals, DW added a Dual Bearing Spring Rocker, making the 5000 quicker and more responsive than ever. And finally they added the dual-chain Accelerator drive system, with an eccentric motion that creates an indirect relationship between the sprocket and the footboard, shortening the length of the stroke, and increasing velocity and sensitivity. Featuring a host of refinements and upgrades, the legendary 5000 Series Bass Drum Pedals still feature aluminum hex shafts, pedal plates and linkages, DWs patented Delta Ball-Bearing Hinge, and the versatile Two-Way Beater.
