Tama HP600DTW Iron Cobra 600 Double Pedal Duo Glide&nbsp;makes it easy to switch between the Power Glide cam and&nbsp;the Rolling Glide cam, which provides a smooth feel throughout the stroke. This double chain drive offers smooth and accurate motion in any situation. Newly Designed Hinge&nbsp;uses a tough, cylindrical brass sleeve to protect the hinge pin from damage or undo pressure, and fluid motion.&nbsp; Speedo-Ring&nbsp;eliminates another source of friction&nbsp;and has a high quality ball bearing built in. Para-Clamp&nbsp;rotates with the angle of the bass drum hoop so your pedal stays flat on the floor.
