The DW 5002TD3 Turbo Chain-Drive Double Pedal is a center double pedal with chain drive system. Featuring a host of refinements and upgrades to their original, performance-proven design, the legendary DW 5000 Series bass drum pedals have remained "The Drummer"s Choice" and the standard of the industry for over a quarter of a century. With aluminum hex shaft, pedal plates and linkages, dual/side adjusting hoop clamps, 2-way 101 beaters, and built-in spurs, it can be customized to fit the needs of any player." Its patented Single Post Casting design provides ease of movement between the pedal and hi-hat, also allowing the pedals to be played independently or simultaneously.
