Thanks, Jacco! I already started disassembling the bike so I can clean the frame and the parts. I want to keep it more or less original but want to change the handlebars to drop bars. I am not sure if I am gonna keep the plastic Simplex group.

I do have a tool for Stronglight cranks, however I realized yesterday that I do not own a 16mm socket to remove the crank bolts so i couldn't procede with the cranks
