About a five second internet search would reveal the winner of the 1977 TdF rode a Peugeot. And not with this set-up either.
Very nice vintage Raleigh Competition GS this is the same bike and setup that won the 1977 Tour de France. Made in England. Campagnolo drive train, Brooks leather saddle. Tires are old and need replacing. Overall very good condition-- a true collector bike. 57 cm.
