lol, I can't get that idea out of my head now. Now I'm wondering which single gear crankset would be compatible with an 8 speed chain and a rear derailleur. Also, what kind of chainline you'd need. And which brake levers would be compatible with those kinds of brakes. Or, even if you cand find road brake levers that are compatible with disc brakes. I don't know if you can find just the right side bar end shifter. Anyway, in the future I might really look into it.
