Tama Iron Cobra HP90P 1st Generation Power Glide Single Pedal 1990s is a rare find. The single drive chain design is more common, but it is hard to find one of these. Original single pedal power glide version from 1994 1996/97 saw the redesign to the current all black model. Pedal has low use time and is smooth and quiet with lots of life on the beater.
