Some more photos of the Paramount. I re-installed the original Campy Record Pista 50T chainring, which has a reinforcing shoulder on the inside of the chainring. The chainring I removed was a less expensive Sugino Mighty Track chainring that lacks the shoulder. I used a whole set of the Sugino chainrings ranging from 46 to 51 teeth to save money in the day, since using the expensive Campy parts would have been cost prohibitive at a time when I didn't have a lot of money.
