I've got an idea, i wonder if anyone has tried it:
Make a SS with a triple crank on the front and a FD, then throw an old RD on the back to act as a chain tensioner, but then instead of just the single rear cog throw a dingle on there so you have two in the back, or maybe even an old 5 speed thread on freewheel so you basically have 15 speeds on your SS
has anyone tried that??
Next you are gonna suggest that some wizard create some sort of shifting device that allows one to traverse these "15 speeds" on the fly. Hahahahaha! Right. While we are wishing let's wish for 20, heck 22 speeds!
Keep wishin, buddy.
