I picked up these same crank arms a couple of years ago off ebay. The seller didn't know what he had (and I didn't know what I was buying). They had a couple of worn out Nuovo Record rings mounted. I think I paid about $30 with shipping.

At first I used them on my '62 Schwinn Continental, just for the fun of it.



After I found out they were at the end of the line for this model, I decided they were perfect for the '72 Super Sport, "Sporty" build. I needed a triple for these NH hills so I ended up using the TA triplizer and TA rings to come close to that original Super Record look.
