Nishiki’s first mountain bike was called the Bushwhacker and it debuted around 1983/84 timeframe. The Cascade rolled out in the late 80s. Consider doing a SS build, not much to it, if everything else is good to go, just take off the rear cassette and get a BMX style rear cog (screw on with it’s own bearings) and strip the front cranks down to just the middle ring. If that thing has chrome Moose bars, it will look pimp!
