Great post Aldo, luv the movies of you shifting... one small point, I believe the 1949 single lever (called the Paris-Roubaix after April 1950)) came with oval-ring on the cone shaped adjusting nut, not the frankenstein bolts. Does anyone know for sure what style adjusting nut originally came on the Paris-Roubaix derailleur?
