hmmmm does the 19" tire end up the same size as a normal 20" ?? i sent my broken uni in a week 1/2 ago, and i hope they give me a brand new uni, that would be the most awesome thing, i broke the seat, frame, seatpost clamp...was the wrong size... the frame was crooked to begin w/, the bearing caps were messed up, ohh and btw, aren't you supposed to use the spacers they send w/ the uni to center the wheel?
