Tx!
I don't know, may have been 60-61 as the modern Paramount's seem to not have come with them. This one did come with it, it was available on road and track.
59 was the crossover year when a lot of things changed and Schwinn started using the top of the line foreign parts that were becoming very popular and necessary to compete at the races and in sales.
Here's a good article about some of this.

And one of my original threads.

They are called Schwinn Paramount adjustable sliding stem, double sliding stem, Major Taylor stem.
It is Schwinn branded as is the SP and brake calipers, HS is Schwinn but is not branded, complete wheels are original as is the paint.
This was a huge get for me, price was not bad, it shares my birthday and is the only one I have seen that was/is this original and complete that I could have ever gotten my hands on.
It's the flagship of my Paramount's that currently number at 5.
