DW reengineered the pedal that established its reputation for innovation and quality. Because innovation is part of DW's DNA they thought it was time for some major improvements. Most notably, the toe clamp. The 5000 needed more gripping strength, providing a stronger connection between the drummer and kick drum. So, they developed the Tri-Pivot Toe Clamp. Three independent 360°, rotating rubber pads firmly pinch almost any diameter and thickness bass drum counter hoop from the top and the bottom, with zero slippage. Add to that a new textured rubber grip pad on the base plate - there’s never been a better system for attaching a pedal to a bass drum. Last, but certainly not least they added a Dual Bearing Spring Rocker, making the 5000 quicker and more responsive.The Turbo™ (TD4) concentric drive system maintains a direct relationship between the sprocket and the footboard to provide a solid, powerful, consistent feel and response.DW Drums DWCP5000TD4 Features:DW’s patented Delta Ball-Bearing Hinge is a state-of-the-art lightweight aluminum design that incorporates ball bearings at both sidesThe AD4 and TD4 pedals feature a Dual-Bearing Spring Rocker delivering ultimate smoothnessThe NewTri-Pivot Toe Clamp ensures the pedal and drum stay connected no matter what hoop size or angle.
