 The Panasonic Sport Deluxe utilized Suntour and Shimano group parts such as derailleurs, shifters, and crankset.The Sport Deluxe frame was originally built out of double-butted 1020 high-tensile steel, though bikes produced in later years may have frames of butted chrome molybdenum steel alloy.All production of Panasonic bicycles for the U.S. market ended in September 1989, following the death of National/Panasonic's founder, Konosuke Matsushita.
