A little more detail on the rear rim of a 1964 Stingray.
It was another mid-year change as Schwinn was known to do.
The 36 spoke rear wheel was used into Aug. of 64.
The 28 spoke rear wheel started in Sept. of 64 and continued for the following years.
BTW, the Copper Deluxe and the Lime Standard "both" have the 36 spoke rear wheel on the last page of that catalog - as they should!
