I donít know if this is a question about a Classic or not, but here goes.
When I was a kid in the 50ís and 60ís the only bikes we knew about were the "regular old coaster bikeí" that every kid on the block had. It was 20, 24, or 26 inches (tires). There were no gears Ė just one chainring in the front and one cog in the back.
Hereís my question: What was the standard gearing ratio or gear inches of those bikes? What would be the equivalent gear setting on my 28/42/52 triple with a 13-26, 9-spd?
