1964 Varsity “Due Diligence” on the Sprocket, Rear.
It pays to do the ^^^^ before you take someone’s advice to look for the “correct” Sprint branded Atom with splines.
There are MANY members on this fantastic CABE site with great knowledge, but not one person has seen every ‘64 Varsity build.
The January 1964 and January 1965 Schwinn parts catalogs mention two different part numbers on the “Sprocket, Rear” for the Varsity.
1964 - #3811
1965 - #3829 (will replace cog #3811). This New type cog - with the internal spline is shown in the ‘65 catalog as a Sprint Splined rear sprocket.
Look at all the dates on the Schwinn catalogs, plus the Schwinn reporter and it’s understandable the Atom two notch 14-28 sprocket would show up on a 1964 Varsity.
Personally I would like to find more information on these two different cog part numbers, plus the early 60’s bikes they were used on.
But for now I’m certain the 14-28 Atom on my F4 Lime Varsity is correct.
Further investigation from 3 years ago on this site shows a 1964 Conti with the same cog as mine. Search member (BillRays) and have a look as someone was in shock this Atom was on this bike ….. “if you haven’t noticed”.
