The SA shifter is for a 2 speed, so I don't think the "49" dated 3 speed goes with the bike, thinking it is supposed to have a coaster or at least 2 speed older rear. Wheels are pitted pretty badly anyway, but man is this bike cool. Brought it home yesterday after it floundered on the local CL, buddy of mine was trying to sell it for a while. I don't know why I didn't get it sooner. ?? :?
