With contributions by Ron Shepherd, Raymond Henry. Front Cover Photo: Fausto Coppi and Gino Bartali slugging it out on the Iozard during the 16th stage of the 1949 Tour de France. Although Bartali, using a Cervino derailleur, is leading here, it was Coppi, riding a bike equipped with a Simplex derailleur, who went on to win the Tour that year. Histoy with detailled drawings photos and lots of technical informations. Outstanding!
