The 1960 Schwinn Varsity had flat-bladed forks and a 15-18-21-25 four-speed freewheel, while the Continental had tubular forks and a 15-17-19-22-25 five-speed freewheel.
By the next year, the Varsity was a 10-speed, as well.
For a number of years, Regina and a few others made only 4-speed bodies, and the optional 5th cog was screwed directly into the 4th, as mentioned above.
