Also those levers are going to be fairly expensive, talk to a local bike shop about pricing before you make any decisions.
what if the friction shifter is not on the frame? I saw some old bikes that have shifters on the center of the handle.( front and back shifter)
I dun think that kinda friction shifter is drilled into the frame. it's just wrapped around the bar.
