This is the third of five Schwinn adverts in Boy’s Life magazine that capture a historic point in the history of the derailleur - the point at which derailleur bikes became mainstream mass-market products sold to ordinary folk rather than to cycling enthusiasts (although there must be a question mark over whether the apple-cheeked, but crazed-eyed youth pictured can be regarded as an ordinary person).
For the 1962 model year Schwinn offered the 10-speed Continental, the 15-speed Super Continental and the 10-speed Varsity. They ditched the pull-chain Simplex Tour de France derailleurs and adopted the avant-garde Huret Allvit with its parallelogram design. Even the front derailleurs are cable operated. These are the first truly modern, truly mass-market derailleur road bikes. If only their frames hadn’t been quite so hellish...
I find the Super Continental particularly astounding. In Britain we did not get mass-market 15-speed bikes until the early 1980s, and even then they did not sell until the arrival of the mass-market mountain bike.
