Joe , I think you are absolutely correct , about some folks being educated in the U.S.A. , with the selling of the Schwinn Sierra , 15-Speed bicycles , in 1963 & 1964 .
However , basically the same bicycle was also available the year before , as the 1962 Schwinn Super Continental 15-Speed .
And , all three of those years , the cranksets , chainrings and all , were all-steel . The cranks themselves were indeed one-piece , Ashtabula-style . Chainrings were 40 - 47 - 52 teeth . The cranksets were listed as being made by Huret .
Once again , as mentioned before , the big change for Schwinn occurred for the 1960 model year . The derailleur-equipped Varsity and Continental bicycles were unleashed onto the unsuspecting public in 1960 . It was amazing stuff ! And they used the Huret , double-chainring cranksets , mostly with 47 - 52 teeth , through 1963 .
The double-chainring Huret cranksets were replaced in 1964 , with the much-much better looking "Sprint" "Made-In-France" cranksets . The old Huret triple hung on for 1964 , and then vanished .
So , my question is this :
If those first cranksets , both double and triple , 1960 - 1964 , were made by Huret , then who made the "Sprint" "Made-In-France" cranksets , 1964 - 1968 ????
P. S. - The 15-Speed idea re-appeared at Schwinn with the hand-fillet-brazed , 1968 Schwinn S/S Tourer , featuring an aluminum alloy cotterless crankset . That model was only available for that one year . The 15-Speed Schwinn Sports Tourer was made from 1971 through 1975 . And the 15-Speed Schwinn Paramount was made from 1970 through 1979 .
