9 spd on a 7 frame - that means cold-setting the frame?
I was figuring to replace the 7 spd setup with a new 7 spd wheelset for the Puch if i didn't get a "new" used 9 spd bike, so i would not have to replace shifters etc. I suppose the Peugeot can soldier on as is for now until it needs a new wheelset.
