actually, i think it's pretty cool that from a single seller you can get an 11-38 8-speed suntour freewheel - custom hot-rodded with a TA chainwheel riveted to the outer cog of the freewheel - and a 28-58 TA quad chainwheel.
This gives you a 32-speed (more than campy or shimano can offer, even today), and gear ratios of 20-142, ready to climb any mountain and/or (almost) set a new land-speed record behind a pace car. seller is even offering a huret duopar with which you may attempt to utilize all of these gears !! *grin*.
